System.out.println("Show the circle");
}
}

Answer / ramyathillainathan
We can indicate that a method must always be redefined in a sub class , thus making overriding compulsory. This is done using the modifier keyword abstract in the method definition.
example;
abstract class Shape
{
------------
------------
Abstract void draw();
------------
---------------
}
