I have begun a class called Die, intended to represent a single standard 6-sided die. You can get the code for Die from Die.java. Create a new project, create a new class called Die, and then paste my Die.java code into your own Die class source code. You will see that most of the methods are stubs--that is, they do essentially nothing. Your job is to fill in the stubs with code that does what the comments describe. You may modify main any way you wish to perform whatever testing you need..
Start early, have fun, and keep in touch.
