final Class

A final class is a class that can’t be used as a base class. To declare a class as final, just add the final keyword to the class declaration:

public final class BaseBall

{

// members for the BaseBall class go here

}

Then no one can use the BaseBall class as the base class for another class.

When you declare a class final, all its methods are considered final as well. The final keyword isn’t required on any method of a final class.
