It's good question because of most of people can't explain why we can't have abstract final classes in Java. Most of them says "An abstract class is of no use if it cannot be extended or instantiated". Imagine class where we have 10 static methods and we want them to be final to never be overridden. Now, because of class have only static methods,we can make it abstract and because of restriction on overriding, we can make it final. So abstract final classes can be very useful in aforementioned cases. But we can't have abstract final classes in Java just stupidly because of Java do not let us. And this is one of many silly restrictions of Java.
