Chapter 6 - Methods Flashcards
means paying attention to important properties while ignoring nonessential details.
Abstraction
the process of breaking down a large program into modules
Modularization

Reusability
includes the method identifier and possibly other necessary identifying information.
Method Header (methods declaration)
contains all the statements in the method.

Value
