If we sish to prevent the subclasses from overriding the members of the superclass, we can declare them as final using the key word final as a modifier .

Example:

final int size=100;

final void show(){…….}

Making a method final ensures that the functionality defined in this method will never be altered in any way. Similarly, the value of a final variable can never be changed. Final variables, behave like class variables and they do not take any space on individual objects of the class
