Try to insert a call to super() as the first statement in the method method() declared in class Test.
Be advised that this is not going to work for the fun() method since it is abstract in class Best, and thus, it is not invokable.

Is this the only way to access the method of base class.
If so then "class Test" is not overriding the method().
There is no concept called overriding method for abstract class
Is that so, correct me please if i am wrong

Hi,Badrinath
how to call a method of abstract class?
in your code
you can use
Best.method();
to call the method of super class

Siu,
method() is not a static method, and thus, you need a reference upon which to invoke it. The statement Best.method() will not compile.

hi Valentin
yes, I omit to see that part of the code because the code is too small
thanks for your help to make it clear

In the method method() of class Test, insert super.method();

There is no concept called overriding method for abstract class

method() in Test overrides method() in Best.
A method in a subclass overrides an abstract method in a superclass or superinterface if they have the same the signature and the method in the superclass is not private and is accessible from the subclass. (See JLS 8.4.6.1)

if i write super.method() in the method() of class Test, then i am calling both the methods of class Best and Test for which overridding is not necessary and more over it is not the "OO" concept of overriding. I can call the method() of class Best from any other function in class Test by using super.method().
So, overriding concept still exist in abstract classes.
thanks

Yes.
super.method() is the *only* way to access an overridden method from code in the subclass.
Compare casting �this� for fields and methods:
