Merry Crismastmas!!
I have a doubt like this:
Why java.lang.Object class is concrete class? Why not it is a abstract class?
What could be the reason behind making it as a concrete class??
Please clarify my doubt....
Thanks in advance!!

Java Designer might not be wanted to force you to override a method from object class.

That can't be the reason; an abstract class does not need to have any abstract methods that you would be forced to override.

fine. but what is the need to make a class as an abstract, if the class does not have abstract method?

Because a class may still represent some abstract thing that you don't want to be able to instantiate directly, even if it doesn't have any abstract methods.
Back to the original question: I guess that is just how the Java language designers chose it to be. Someone posted a long answer here: Why java.lang.Object is not abstract?
