I've written a Java "prior knowledge test", it seems that in addition to the exam I already wrote, I also have to do the following:

Quote:

The applicant should submit a copy of a program(s) written in Java
that illustrate the use of a class and a �tester�. The class
should have:
o At least 2 instance variables
o A constructor
o Several methods, including accessor methods and several
additional methods that illustrate passing of parameters.

I know this is an easy "easy" assignment. However, what the heck is a tester? Is it the main method "with code" that creates an instance of the class that I'm writing? Please help me in clarifying this.

Yes. You write code to test all the various, designed operations of your application. It's how you know the design is worth a crap. Professionally speaking, you would at least define these loosely after designing the app, and before you wrote the code for the app. Then you would code the tests to do their predefined functions.
