A '''final . All methods in a final class are implicitly final. Example: public final class MyFinalClass {...} A final Method cannot be Overridden by subclasses. This is done for reasons of efficiency, since the method can then be placed Inline wherever it is called. Example: public class MyClass { public final myFinalMethod() {...} } A final Variable is a Constant . It must be assigned a value at Declaration , and the variable can later be used but not assigned a new value. Local Variables (for example, variables in loops) cannot be declared final. Example: public class MyClass { public static final float PI = 3.1415; } |
