In this assignment you'll be using what you've learned about Java to implement a library of static methods. Please read and follow the directions carefully! In your assignment project, add a package a2. Import starter code from this Google Drive file https://drive.google.com/file/d/1dP9r4RlvlwlXEX4kXbwrKxFBXB3S7CNp/view?usp sharing e It contains method stubs (the signature and a method body which returns some default result) and comment descriptions of several methods for you to implement as well as an already implemented method to help you for one problem. The method stubs are precisely specified in their comments and/or method headers. Your job is to implement the methods so that they adhere to their specifications. These methods will exercise much of what you've learned about Java. You will be using primitive values (such as ints, booleans, and chars) and objects (such as Strings and Scanners). You'll be using lots of different kinds of expressions. You'll be using a variety of statements, such as variable declarations, assignments, while loops, conditionals, and returns Be sure to add your name as the author to the Javadoc comment associated with the class. The comment on each method you implement should be replaced with a more formal Javadoc comment using @param and @return tags. Notice how I have chosen descriptive names for all classes, methods, and variables. If you want full credit, you should do the same with your code. Notice how my code is nicely formatted. Your code should be nicely formatted too. (If you type ControlOrCommand-Shift-F Eclipse will format your code for you.) You will almost certainly find this more challenging than A1. Some of the methods require you to be very comfortable with things like substring and joining strings together with +. Some of them are quite short but you will need to be clever about how to solve the problem. Others will need you to look up certain Java operations so that you can use them comfortably. Please start early so that you'll have time to think and ask questions when you get stuck. Starting on Wednesday or Thursday is a recipe for failure. You will also notice from reading the comments that you need to add code to main. This is mostly for your benefit - you need to call your implemented methods to see if they work. But, provide output and descriptions that explain what is going on. For example, your main method might call want to test countTokens("l am David"). Your code might have String testString-"I am David"; int numberOfTokens countTokens(testString); System.out.println("countTokens found" numberOfTokens+"on test input: " + testString); When you run your program with more of these tests, you would see a sequence of these reports on the method behavion Submitting To turn in your program for grading, upload the .java file to assignment 2 in Gradescope. You will see a number of tests pass or fail. Additional tests and TA evaluate will happen after the due date You can upload a solution as many times as you like, but we will only grade your most recent submission. his tool needs to be loaded in a new browser window Returns a string literal "negative" if the parameter is less than zero and equal to zero For example, the method call deacribeSign should return "non-negative" You should use an if statement You must return these strings exaczly (all lower case letters, spelled denote a string literal, they do not appear in the actual string Do not print the string return value * returns the string literal "non-negative" if th value is greater than or *correctly, no extra spacesAlso note that the double quotes are used to * Replace this comment with your own Javadoc comment public static String deacribeSign (int value // Chang or modify the return.

This ia here for now to prevent compiler errora return true; *Returns a String of length width that begins and ends with the character edge *and contains width-2 copies of the character inner in between. For example, * if edge is +inner is '-*, and width is 8, the method should return The method does not print anything. The parameter width must be greater than or equal to 2 IMPLEMENTATION NOTE: This method is already completely implemented.
