Starters Today you will implement the collections algorithms for the Half Marathon program. You will use an ArrayList which is a type of collection (so it has methods available from Collections). Read about the properties and methods of the ArrayList class Read the example how to sort an ArrayList Main Activity Open your _java workspace on cloud9 Dowload the Marathon.java program Or from a terminal window wget hwmath.net/IBCS/files/Marathon.java Download the data file Participants.dat using wget: wget hwmath.net/IBCS/files/Participants.dat The Marathon class contains the following ArrayLists: ArrayList PARTICIPANTS = new ArrayList(); // max number of participlants = 450 // contains the name of the team they are on ArrayList TIMES = new ArrayList(); // The finish time of each runner ArrayList TNAMES = new ArrayList(); // if each team had the min of 150 participants ArrayList TEAM = new ArrayList(); // links team members together Review the main program public static void main(String[] args) { Marathon half = new Marathon(); try { half.loadParticipants("Participants.dat"); half.findTeams(); half.linkTeams(); half.printTeams(); } catch (Exception e) { System.err.format("Exception occurred in main program"); e.printStackTrace(); } } Review method loadParticipants() and see how the input file is processed and the ArrayLists PARTICIPANTS and TIMES are initialized. Review the method findTeams() and see how the list of PARTICIPANTS is traversed to create a list of TNAMES which contains a list of all of the unique team names. Assignment 1: Complete method linkTeams() to make a "link" between each member of a team. See the handout from last week for more details. The list of teammates is circular, so if you start at any index you should be able to find all of the members who are on the same teams. Assignment 2: Complete method printTeams() to print the name of each time on a line with the indexes of all other participants who are on the same team. Challenge Assignment 1: Modify the printTeams() method to also print the teams competitive time: teams are comprised of 3-5 team members, the sum of the lowest three scores on a team becomes the teams time. Challenge Assignment 2: Have your program identify the teams that came in first, second, and third, along with each teams time. Summary ArrayList methods that you should have used today: .size() .get() .add() .indexOf() and possibly a sort method somehow Homework Collections Complete the Marathon.java program Update Google Class Room when you have completed the assignment.

Starters Return OSI Model Quiz Handout: Tracing a recursive program Main Activity Presentation: Recursion Evaluating multiplication as repeated addtion Evaluating exponential expressions using recursion Java Assignment Your _java cloud9 workspace will be backed up at the end of the class and must reflect a class period's worth of effort and progress. Write a recursive algorithm to evaluate a power, given the base and the exponent. create a recursion directory in your cloud9 _jave workspace create a file name Recurse.java write a method named rexp that accepts two integer paramaters rexp(b,e) and returns the value of b raised to the e power. Example: rexp(5,2) returns 25; rexp(2,5) returns 32; Write a recursive algorithm to multiply two numbers, using repeated addition. In the file Recurse.java write a method named rmult that accepts two integer paramaters rmult(a,b) and returns the product of a * b. Example: rmult(5,2) returns 10; rmult(50,20) returns 1000; Write a function named half that accepts an integer and returns half its value. Write a function named doubleIt that accepts an integer expression such as (a+b) and returns a value as if the expression were repeated twice, such as (a+b)(a+b). Write a function named isOdd that accepts an integer and returns true if the parameter is an odd number, and false if the parameter is not odd. The efficiency of the recursive algorithm that you wrote for rexp is probably linear - which means if you had an expression to evaluate 210 it would execute 10 times, and would vary linearly as the exponent increases. Write an algorithm that uses doubleIt, half, and isOdd that can evaluate a power with logarithmic efficiency. Write a method named rexpL(b, e) that can calculate be in logarithmic time. Homework Due Wednesday Be prepared for quizzes covering all network topics - particularly topics that you have seen at least twice. The completed Recurse.java assignment reflecting all 11 steps. Add your documented algorithms as comments to your Recurse.java file. Be prepared to spend at least 1/2 of the class Wednesday making progress with your Internal Assessment project.

This is a topic worth thinking about. Think about the vocabulary for the topic "searching the web" and how that vocabulary applies to answering this question. Here are some things to consider: What is a search engine? How does a search engine work? If you were creating a search engine, what are the assumptions that you would make? Who are the targeted users of search engines? Who are the content providers for search engines? Do all content providers follow the "rules?" What are the rules? As a search engine designer, what "rules" would you want to your content providers to follow? What would you do with content that doesn't follow the rules? You need not write an essay (because the command term is Explain, but connect some of these ideas while addressing the question directly. Read the question again carefully and pick some key concepts to include in your answer. Homework Prepare for the test tomorrow Friday January 6

Starters Handout: Binary Tree - Concept Review Test Drive Word Study Binary Trees This is flash-card app that can Display a vocabulary word so you can think of the definition (and check your answer) Display a definition so you can think of the term (and check your answer) Display both a term and defintion so you can review vocabulary Test Drive Word Quiz Binary Trees This all will loop through the select vocabulary lists twice: The first time through will show you a vocabulary term, and have you select the correct definition The second time through the list you will be shown the definition and you will select the correct vocabulary term. At the end of the quiz you will be shown the results for both passes through the list. Main Activity Text Indexing Lab In this exercise you will take your program that counts the individual words in a file to create a binary tree, and print the binary tree inoder, preorder, and postorder. You will be able to use a WordTree.class that has already been developed: your job will be to integrate this program with yours. First, in your Cloud9 java sorkspace, create a top-level directory named trees. From a terminal window, use the web crawler wget to download a tar file with the necessary program files. cd trees wget hwmath.net/IBCS/files/binary_tree.tar tar -xvf binary_tree.tar This command extracts all of the files like unzip ls -l Complile and test the Words.java program Change the Words.java program and replace all occurences of the word list with the word tree including the comments and variable names. Copy your countWords.java program, and any files used or needed by countWords.java, into the trees directory. Add a declaration to the program to use the WordTree class WordTree my_tree = new WordTree(); To insert a word into the tree use the insert method public void insert(WordNode List, String s, String s2) { You can find an example of this in the Words.java test program. You can use a blank string for either the second or third parameter. In the Words.java program the second parameter was the city, and the third parameter was the state. When the tree node is created these two strings will be concatenated and stored as a single string. The method WordTree.top() returns the first node in the list. Examples of using the methods for printing the tree can be seen in Words.java printWords_inorder(my_List.top()); printWords_preorder(my_List.top()); printWords_postorder(my_List.top()); printWords_reverse(my_List.top()); Intgrate calling insert() and printing out the lists into your countWords.java program. Compile, test, debug, repeat as needed until you have a functional program. Test you program by passing it a small file, and then a large text file with hundereds of words. Summary: What you need to know - and what you need to be able to do Know all binary tree terminology Know how to traverse a binary tree inorder, preorder, and postorder Homework Due Wednesday: Come to class prepared to work on your Internal Assessment Project: You will be working on completing Part B and designing your solution. Due Wednesday: Complete the classwork from today: creating a binary tree from the words that you have read from a text file, and printing then out inorder, preorder, and postorder. Due Thursday: use the WordTag app enough to pass a Binary Tree Vocabulary Quiz Due Friday: Chapte 7 of the AP Computer Science Book Do problems 1-6, and then choose one of problem 7 or 8.

Starters Quiz/Test - 15 points Silence is demanded until all students have completed the Quiz/Test. Any talking will result with a score of zero and dismissal from the class until the quiz/test is complete. Main Activity Using Text Files with Java Review the file TextProcessing.docx (MS Word file). If you do not have a writeHello.java program in your java work space, copy/cut/paste the writeHello.java program from the one in the file - read all of the information in the file so that you can compile and execute the program. Create a file named writeHello2.java, and either copy your writeHello.java program into it, or use the one from the TextProcessing.docx file. Change the file name so that an exception is generated and the catch block is executed. Change the text message that is displayed when an exception occurs. Complete the programming assignment from Monday : In your Cloud9 java environment create the following programs: writeHello.java - that will open a text file for output, and write a single line of text to the output, and closes the file. readHello.java - that will open a text file for reading, read each line in the file, and display the text of the line on the screen. Test this program using the output created by writeHello.java countLines.java - that will accept a command line argument that specifies a input file name to process, opens the specified file for reading, and reads the input file and counts the number of lines in the file. The number of lines in the text file is displayed to the user along with the input file name. Create a progam named countWords.java modeled after countLines that will parse each line in a text file, and count the number of words and the number of lines that are in the text file. Parse each word by a space or punctuation character or end of line. Allow a word to contain all numbers, all alphabetical characters, or numbers and letters. The program should accept an input file name as a parameter and display both the number of lines and the number of words in the file. Compare your result with the result of the Linix wc command. Summary: Make-up Quizzes - today before 2:00. I will be in the library. Possible Quiz/Test on Thursday Homework Complete countWords.java by Friday - it will be the basis of your next text-processing assignment.

Starters Introduction to Stacks Introduction to web crawlers Class Notes What is a web crawler? Main Activity After getting some really great feedback today in class and to focus on using a linked list to implement a stack, we'll limit the methods inside of the StateNode class to the following: //File: StateNode.java //Purpose: Support a linked list of state names public class StateNode { public String state; public StateNode next; StateNode() { state = ""; next = null; } StateNode(String s) { state = s; next = null; } public String toString() { return state; } } // end StateNode Using a Linked List to Implement a Stack Next - well create a new class that will use StateNodes to create a stack. The StateStack class will keep a variable named stack and will be used like the list variable had been in class. Some of the StateStack methods are left for you to implement, they will be only a few lines long. The basic stack operations are: push - which adds a new node to the linked list. Because we are implementing a stack, new nodes should be placed in the front of the list. pop - this has two components: the top node needs to be returned, and the top node should be deleted from the stack. In terms of a linked-list, the first node in the list should be removed. peek - this method simply returns the node that is on top of the stack (which is the first node of the linked list) //File: StateStack //Purpose: Implement a stack of StateNodes // using a linked list public class StateStack { private StateNode stack; StateStack() { stack = null; } // let someone test to see if the stack is empty public boolean isEmpty() { return (stack == null); } //pop : return the top node of the stack, and remove the top node // from the stack. public StateNode pop() { // implementation is up to the student } //push : Add a new node to the stack public void push(String s) { // implementation is up to the student } //peek : return the top node of the stack. public StateNode peek() { // We'll return the top node, which will still be connected to the stack return stack; } public void printStates() { StateNode tPtr = stack; while (tPtr != null) { System.out.println(tPtr.toString()); tPtr = tPtr.next; } } // end printStates } // end StateStack Creating a new version of States.java to test the StateStack class and the implementation of a stack of states: //File: States //Purpose: Create a stack with 5 state nodes // This is a demonstration of using stack operations public class States { public static void main(String[] Args) { StateStack my_stack = new StateStack(); System.out.println("Adding first state: Maine"); my_stack.push("Maine"); my_stack.push("New Hampshire"); my_stack.push("Vermont"); my_stack.push("Rhode Island"); my_stack.push("Massachusetts"); my_stack.printStates(); StateNode j = my_stack.pop(); System.out.println("poped val = " + j.toString()); my_stack.printStates(); } // end main } // end States Notice that the main program uses push to add five states, then printStates() to print the contents of the stack of states. Next the stack is "popped" where the top node is placed into variable j (not the most cleaver variable name) and then the stack is printed a second time. The output of executing the program should be: Adding first state: Maine Massachusetts Rhode Island Vermont New Hampshire Maine poped val = Massachusetts Rhode Island Vermont New Hampshire Maine To DO: Modify the StateStack.java and States.java programs: Move the printStates method to StateStack.java from StateNode.java Modify StateStack.java and implement the push, pop, and peek methods.

Starters Homework Review Chapter 2 #1-2 Solution (.notebook file) Main Activity Create a flowchart or pseudocode for each of the methods of the Time class from problems 1-2. In your java workspace that you have shared with me, Implement each of the methods from the Time class from problems 1-2. The toString method must return a string that will display similar to a digital clock. For example: 12:04:39 Create a main program to test your Time class: declare at least two Time objects to test your constuctors Create a final variable named timeSpan set to 51 which represents a number of seconds. Create a loop that will call increment() timeSpan times. Create a second final variable named numSpans. Create an outer loop around your timeSpan loop, which will repeat numSpans times. Test your program using numSpans with a value of 5, then set numSpans equal to 75. Your program will be evaluated when numSpans is set to 75, Call toString so that the time is displayed (like a digital clock) every time that increment has been called 51 times. Pseudocode for the main program Time T1 = 9:10:00 /* figure out how to do this */ Loop I from 1 to numSpans Loop J from 1 to timeSpan call T1.increment() end J loop output T1.toString () end I Loop Hint: don't start coding anything before you write it out in pseudocode or a flow chart first.

Starters View Nearpod presentation Class Decomposition Self-paced, code: BIHCX but the link should take you right to it. Purpose: Trace a program simulating the rolling of two dice. Notice what methods are provided by Class Die and how thee are used by the main program in RollDice. Main Activity Box Introduction: In this exercise you will complete the class Box that calculates the area and volume of a cardboard box. Programmers often use preconditions and postconditions when describing the behavior of a method. Precondition - is a requirement that a user of a method must meet inorder for the method to work properly. For example, in a banking class a deposit method might have a precondition that a deposit can't be a negative number. If the deposit method is called with a negative number the method would not give correct results. Postcondition - is a statement that indicates what will be true when the method finishes its work. It is a description of what the method does. If the precondition is met the method promises that its postcondition would also be met. Directions: In your cloud9 java workspaces add Box.java and BoxTester.java to the lessons directory. Complete the following Modifications Instance Variables Create an instance variable of type int named side. Constructors Create a one parameter constructor that initializes side to the value specified in its parameter list. Methods Complete the method calculateArea according to the specifications outlined in its pre and post conditions. Complete the method calculateVolume according to the specifications outlined in its pre and post conditions. Extensions: Modify Box.java to allow a width, height, and length to be specified in case the box is not a cube; but still support a box that is a cube and don't make the main program specify three identical parameters. This means that if you change Box.java then BoxTester.java should still work and still produce the same output. Modify BoxTester.java and create Box instance box4, box5, and box6. Use the same width, height, and length parameters as a partner to make sure both of your programs are successful.

Starters Handout: Identifying Objects App GrossPay What is a property? What is a method? What is an object? Main Activity Discussion: Test 01 Discussion: Internal Assessment Web resource BWagner.org Summary: A method is a group of statements in a programming language that is given a name. Sometimes methods can accept parameters and operate on those parameters. Some methods can return a value, which could be a primitive data type, class/object. In C we called the methods functions, some languages call them procedures. [Some languages will use the term function for a procedure that returns a value and a procedure is a block of code that is called that does not return a value] A property is a characteristic defined for a particular object (or class). An object is an instance of a particular class.

Main Activity Command Line Arguements to Java Programs Read handout: Java Programming Using Command Line Arguments In the cloud9 environment add both Args1.java and Args2.java to your lessons directory. Compile and execute both programs and make sure they both work. How can you get the command line arguements java Args01 I like pie to all be treated as a single multi-word arguement? Keep testing until you figure out how to do it. Processing Command Line Arguements Copy either Args01.java or Args02.java as SumArgs.java Read the examples of converting string numbers to numbers using Integer.parseInt(str) and Double.parseDouble(str) on www.Tutoroalspoint.com. Change SumArgs.java to find the sum of all of the command line arguments that are passed in. Here is a sample run: java SumArgs 1 2 3 4 5 The sum of all arguments is 15 You may format the output the way you wish - but at least display the correct sum :) Summary: The String, Integer, and Double classes provide many methods for accessing and converting data from one type to another. Using and understanding these methods will help us to understand objects in general and the differences between object-oriented langauges and non-object-oriented languages. Homework: Copy your SumArgs.java program as DataStats01.java For homework on Monday September 12 you were asked to create an algorithm using pseduo code for analyzing data. Modify the DataStats01.java program to calculate the statistics that were listed, getting the data from the command line arguments. Lets suppose that the command line arguements are real numbers. If you run into any problems - or have found interesting ways to address any problems, post them in the google classroom.

Starters Vocabulary Matching game (handout) and review of the answers. Main Activity Activity 1: Web Science In this first introductory web science activity you will research the web-meaning of some vocabulary terms that will help you with the Web Science and Networking aspects of the IB Computer Science course and the Case Study. Using the document posted on Google Classroom, but if you can not find it you can download the file: WebTerms-01.docx (MS Word) Follow the directions in the document and on Google Classroom. Activity 2: Java Programming Create a Cloud9 directory named assignments. This directory should be in your root directory and at the same level as the lessons directory - not under lessons. Create a file named stats1.java, and save it under assignments. Implement the algorithm that you completed for homework as a java program. Compile, run/test your program. Use carefully selected data to verify the accuracy of your program. If you get errors or results that you are not expecting review your program, and determine whether you may need to "cast" from one data type to another. Copy the file stats01.dat into file assignments/stats01,dat Execute your program using the following command, which will use the data file as input instead of using keyboard input: java stats01 < stats01.dat Email a copy of your output to jbrennan@isbos.org. Summary: Today you reviewed some basic web science terms, and hopefully made some connects with some daily events with some more formal terminology. Can you name an "ambient intelligence" system at the school? Can you name more than one? You should have gained some experience with loops, detecting the end of input, and maybe had to debug some calculations. Homework: Complete the classwork from Activity 1 for homework, by Friday. Complete the program assignment from Activity 2 by Monday. IF you have problems that you can not figure out in a reasonable amount of time, then ask some questions before the weekend. Post your questions on the Java section of GoogleClassroom Check the questions in the Java section of GoogleClassroom to see if there is some one you can help.
