What is the ';Top Down Design'; in java language programming.?

Simple explanation and example would be greatly appreciated. ThanxWhat is the ';Top Down Design'; in java language programming.?
I think it means breaking up a big program into a bunch of little programs that work together.





For example, a football game is a pretty complicated thing if it were to be programmed. But you can break something big and complex into easier things.





Instead of a football game, Top Down Design would break it into:





2 teams:


team 1


players


ability


team 2


players


ability


score





Kind of like that. You make those one at a time and then integrate them.





Does that help? I'm not great at explaining things.What is the ';Top Down Design'; in java language programming.?
It means that you start with the big picture, with a main program and then break it down into smaller and smaller pieces with more and more granular functions.





Not specific to Java - it's the same for all programming languages.
