Introduction to OOP

Chapter 4: Classes and Methods:

Static and Final

Notice how symbolic constants are defined in Java:

static means that all instance share the same value. One per class. Similar meaning in many languages.

final is Java specific, and means it will not be reassigned. (C++ has const keyword that is similar, although not exactly the same).


    public static final int Spade = 1;
    public static final int Diamond = 2;
    public static final int Club = 3;
    public static final int Heart = 4;
