hi folks ! in head first java author sometimes doesn't uses test classes and puts the main inside the class to be tested . is it the same thing as putting the main in some other test class. what if there are many objects of that class i.e many main functions. I know static has to do something with it. can anyone please help
Yes, you are right, its the static part that ensures that for all objects of the class of that particular type, inside which a static variable or method exists, only one copy is made and is made available, the same copy, to all the objects of that class type. Can you please give any example from the book for reference?
