6.15 *zyLab: Calendar (Required & Human Graded) This code works but there are some problems that need to be corrected. Your task is to complete it to course style and documentation standards as described in the CS 200 Style Guide. This project will be human graded. This program takes as input the year and the day of the week of January 1st and generates a calendar for the whole year. Getting Started Set up a Calendar project in your IDE (Eclipse or IntelliJ) • Download Calendar.java, put it into your project and make sure it compiles and runs. Note: The provided code works. The goal is to refactor, improving the code while keeping it working. Add a file header comment. Turn in the code to zyBooks to make sure the tests pass. Style and Format each of the methods Format the method code to follow course standards. The IDES can be helpful, but review to make sure the standards are followed. In Eclipse, select code, go to the Source menu, select Format, and then select Correct Indentation (Alternatively: Ctrl + Shift + F) • In IntelliJ, select code (in editor, Ctrl + A), go to Code menu, select Reformat Code (alternatively: Ctrl + Alt + L) • Verify your program is still working. • Turn into zyBooks to verify your program is still working. Turning in also saves snapshots of your code to return to at a later time if necessary. If at any time your program is not working, then back up to a point it was working and try again. Refactor the identifiers (names) Refactor the method names, parameters and local variables to be meaningful and follow course standards • Meaningful names easily guide someone that is not familiar with the code to understand what the method does or what the variable contains. Variables are typically nouns or noun phrases while method names are typically verbs or verb phrases. Avoid abbreviations unless very commonly used. • In Eclipse or IntelliJ, right click on a variable name, select Refactor, select Rename. Type the new name and the name will be changed everywhere. (Alternatively in Eclipse Alt + Shift +R, IntelliJ Shift+F6) Trace the code using any example inputs to figure out what is happening • Trace by hand, use print statements or use a debugger. If you add print statements to help you debug, remember to remove them later. Verify your program is still working. • Turn into zyBooks periodically to verify your program is still working and also provide snapshots of your code to return to at a later time if necessary. Add Class and Method Header Comments Write a JavaDoc comment for the class and every method following the course standards. Method comments should include a summary description, an algorithm for non-trivial methods possibly including a citation, and @param and @return tags (if there is a return value) with a description. We expect you to use your own words. • Verify your program is still working. • Turn into zyBooks periodically to verify your program is still working and also provide snapshots of your code to return to at a later time if necessary. Notes • Some methods are given to you (getDaysinMonth, getMonthName, main). The only changes that would need to be made to these methods are if they call other methods whose names have been changed. Final Submission • Make sure your code follows all the standards in the Grading Rubric and expectations described in the CS 200 Style Guide. Make sure all TODO items are complete and TODO is removed. Turn in your final version to zyBooks. The latest version that compiles and runs prior to the deadline Thursday, October 15th, at 11.59 pm (no 10% penalty after 6 pm) will be the version that is human graded.
