This is a really, really dumb question but I'm trying to wrap my mind around why all my beginner java books use the main method to instantiate objects of a different class than the one it is being instantiated in, such as the one below. I've tested it and know it works but why don't I ever see it in the books? Is there a drawback to creating a new object of the same object that you are in?
Thanks, Von and sorry if this is a crazy question!!!!!!
public class TestClass
int id = 6;
public static void main(String args)
TestClass firstTest = new TestClass();
firstTest.id = 5;
