Read this entire document before you begin. • This assignment focuses on using the Git version control system, within an Eclipse Environment. • Expectation: you have already reviewed and completed instructions for Git installation and configuration o See Hybrid 05 content area for instructions on Git installation o See Hybrid 08 content area for instructions on using Git within Eclipse ▪ Tip: Hybrid 08 will walk you through this lab assignment as well. o If you have not installed Git, or worked through the handouts for Hybrid 05 and 08 do so now. • This assignment handout has brief step-by-step instructions • You will need to screen shot your running program • You will need to screen shot your Git History for the project in Eclipse • Submit your source code file, and your Git Repository as a zip archive. (and follow Lab Professors Directions) Steps Create a Git Repository for the project (Use Windows File Explorer for this step) • Create a Git Repository folder for your Assignment 3 Project, see hybrid handouts. • Create the following location on your hard drive for the repository: C:\CST8116_Assignment_03_Your_Name Your Name should be your full name, as see in ACSIS separating each name with underscores. • You will need to zip this folder and submit it after completing all of the steps in this lab. Create an Eclipse Project • Name the project: Assignment 3 Add the Project files to the Git Staging area • Add your project to the Git staging area within Eclipse (See hybrid handout(s) for infor- mation on Team > Share Project, as well as how to direct Eclipse to use the repository folder you created above. • Then Right-Click Project and use Team > Add to Index Verify .ignore file • Make sure that the .ignore file has an entry for /bin/ • If you cannot see the .ignore file reference the hybrid handout on how to modify the package explorer filters. First Commit • Commit the initial project files o Enter a commit message "New Project Assignment03 by YourFullName" o Omit the double-quotes. o replace YourFullName with your actual name o Add a signed-off by entry with your name and email using the interface (see hybrid handout) o Commit. Create a source code file and add to version control • Add a class to the project naming it Assignment03 YourFullName where YourFullName is your full name as it appears in ACSIS. For Example Stanley Pieda would name the class File Assignment03StanleyPieda • Check off the box to create a main method. • Right-click on the file and add it to the Git Staging Area (Team > Add To Index) Second Commit • Commit the new source code file. o Enter a commit message "Added source code file Assignment03 YourFullName with method main" ▪ Omit the double-quotes shown on the line above. o replace YourFullName with your actual name o Add a signed-off by entry with your name and email using the interface (see hybrid handout) o Commit. Copy starter code into source code file • Copy the starter code located here (see end of handout for fuller code listing) into method main. • Modify the code so that it prints out your actual name, instead of "Your name" • Add programmer comments to the file in the usual manner for our course. o You will be asked to fix a mistake in the program in a later step. o Currently if you run the program as presented here, it will not produce the correct output. o See the Appendix at the end of this handout for what the program is expected to do, versus how it crashes. int roll 0; int[] diceRolls = new int [10]; int total Rolls = 0; // sample the rolls for (int count = 0; count < 1000; count++) { roll (int) (Math.random()* 10) + 1; diceRolls [roll - 1] = diceRolls [roll - 1] + 1; // adjust 1- 10 value to 0-9 for index = } // run a report for (int index= 0; index <= diceRolls .length; index++) { // crashes System.out.printf("Count of %d is: %d%n", (index + 1), diceRolls [index]); totalRolls totalRolls + diceRolls [index]; } System.out.println("Total rolls were: " + totalRolls); System.out.println ("Program by Your Name"); • Save the changes to the file. (Just normal Save button in Eclipse). Third Commit • Commit the changed source code file. o Enter a commit message "Added programmer comments, starter code in main, added my name." ▪ Omit the double-quotes as seen on the line above o Add a signed-off by entry with your name and email using the interface (see hybrid handout) O Commit. Run the program / fix the bug / run the program & Screen Shot. • Run the program and observe the mistake (it likely crashes) • Fix the problem with the loop that generates the report (see bolded line above marked as //crashes) • Run the program and take a screen shot of the corrected program output for your MS Word document. Fourth Commit • Commit the changed source code file. o Enter commit messages, use Separate lines, blank line between each. "Corrected the problem with the loop." "The loop counter is being used as the subscript for the array, the stopping condition was incorrectly set as index <= diceRolls.length when it needed to be index < diceRolls.length." o Add a signed-off by entry with your name and email using the interface (see hybrid handout) o Commit. Take screen shot of Git history in Eclipse • View the Git History in Eclipse. • Ensure that your Project (not just the source code file) is selected in the Package Explorer so that the full history is shown. (Right-click, Team > Show in history) • Take a screen shot that shows your commit: id, message, author, authored date, commit- ter, and committed date. • This is an example created by Stanley Pieda from a previous delivery of this course.
