30-Mar-2015If subclass (child class) has the same method as declared in the parent class, it is known as method overriding in java.
In other words, If subclass provides the specific implementation of the method that has been provided by one of its parent class, it is known as method overriding.
1-Method overriding is used to provide specific implementation of a method that is already provided by its super class.
2-Method overriding is used for runtime polymorphism
class Vehicle{
void run(){System.out.println("Vehicle is running");}
}
class Bike extends Vehicle{
public static void main(String args[]){
Bike obj = new Bike();
obj.run();
}
}
class Vehicle{
void run(){System.out.println("Vehicle is running");}
}
class Bike2 extends Vehicle{
void run(){System.out.println("Bike is running safely");}
public static void main(String args[]){
Bike2 obj = new Bike2();
obj.run();
}
