This is my goal: Provide Java code for a simple class of your choice. Be sure to include at least one constructor, two methods and two fields. The fields should be private.
Create a test class to constuct and call the methods of your class.
Describe your class and demonstrate your code functions properly.
I created this code and attached the files. However my output is not the way i am trying to get it. Its also pretty long and i dont know how to make it more better because this is not my strongest subject
i would like it to be as follows:
Your book is a: mystery/fiction/nonfiction
your was published: before 2008
you book is: available in hardcover
Your book is available: TRUE AND/OR FALSE
Your book is: Available in less than five copies (if random generator is below 5)
Your book is: Available in less than six copies (if random generator is below 6)
your was published: before/after 2008
Your book is a: mystery/fiction/nonfiction
Here are the codes:
