Where to put classes in Java

a class describes the contents of the objects that belong to it : it describes an aggregate of data fields (called instance variables), and defines the operations (called methods). object: an object is an element (or instance) of a class; objects have the behaviors of their class.

The components of a class, such as its instance variables or methods are called the members of a class or class members. A class member is declared with an access modifier to specify how it is accessed by the other classes in Java.
