The Final keyword is used to ensure that the methods/variables are not modified/overridden in their child classes. ex: public class A { public void final getName(){ ... } } public class B extends A{ public void getName(){ ... } } While trying to compile class B, there would be compilation errors. Since the method getName in the parent class is final, it cannot be overridden in the child class.
