pls help!!

For the following questions, "define a class" means the following . Create an appropriately-named file containing the Java class definition, including the following - A block comment describing the file (and hence the class), as always Any instance variables, as required by the question - Accessor (getter) and mutator (setter) methods for any instance variables - Constructors as appropriate or as required by the question - A toString method that prints instances of the class informatively Any additional methods as required by the question. All methods other than get ters and setters MUST have a descriptive comment before their definition . Create a separate appropriately-named file containing a different Java class with a main method that tests your new class by doing the following - Create at least two instances of the class. Change at least one of them using the class' methods - Print all the objects informatively If you prefer, you may write one class with a main method to test all the classes defined in this homework. In fact, your TAs would probably appreciate it since it's easier to test. Just make sure it's clear what's going on (good comments in code, good content in output) As always, be sure to document how to run your code and interpret the output in your README.txt file
