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
}
