Declaring a constant in Java

 Java does not directly support constants. However, a static final variable is effectively a constant.

    The static modifier causes the variable to be available without loading an instance of the class where it is defined. The final modifier causes the variable to be unchangeable.

    Ex: public static final int FOUNDING_YEAR = 2001;

    Naming Standards for Java Constants
    Although these aren’t syntactical rules, they are widely used as accepted conventions.

    Java constants are normally declared in ALL CAPS.
    Underscores normally separate Words in Java constants.
    Sample Java Constant Declaration
    public class MAX_UNITS {
     public static final int MAX_UNITS = 25;
    }
