Class Definition » Final Class

Final Classes
You can prevent others from extending your class by making it final using the keyword final in the class declaration.

final class FinalClass{


}

 

Using final to Prevent Overriding

class A {
  final void meth() {
    System.out.println("This is a final method.");
  }
}
   
class B extends A {
  void meth() { // ERROR! Can't override.
    System.out.println("Illegal!");
  }
}
