Method Overriding

• If subclass (child class) has the same method as declared in the parent class, it is known as method overriding in java.

Usage:-

• Method overriding is used to provide specific implementation of a method that is already provided by its super class.
• Method overriding is used for runtime polymorphism
  Rules for Java Method Overriding:-
• method must have same name as in the parent class
• method must have same parameter as in the parent class.
• must be IS-A relationship (inheritance).
  Example:–

class Vehicle
{
void run()
{
System.out.println(“Vehicle is running”);
}
}
class Bike2 extends Vehicle
{
void run()
{
System.out.println(“Bike is running safely”);   //Method Overriding
}
public static void main(String args[])
{
Bike2 obj = new Bike2();
obj.run();
}
