Answer / vikas
Overriding means, In a derived class, if we include same
method name, with same number & types of parameters and
return type as a method already defined in the base class,
then the method is said to be Overridden.
base class:
class Circle {
protected double radius;
public double getArea() {
return Math.PI*radius*radius;
}//this method returns the area of the circle
}
derived class:
class Cylinder extends Circle {
protected double length;
public double getArea() { // method overriden here
return 2*super.getArea()+2*Math.PI*radius*length;
}//this method returns the cylinder surface area
}

According to J2ee Compleet reference java:
I Think the answer is that
Overriding means the : In inheritance If we Declare the
(Public of default) Method in the superclass Similarly we
declare the method with the same name ,Same type,same
number of parameters.but the Body of the method May
different When We Instansiate child class and access it
then child's method will called if u want to call super's
overriden method then use the [super()] method to access it
in child for this read [Java compleete reference's
Chapter#8] u will find reasonable answer
