Java Method overriding:

If a method inherited from the superclass requires a different definition other than the definition provided in the superclass, then the method can be redefined or overridden. The process of redefining/overriding the method is called as Java – Method overriding.

The overridden method must have the same signature as that of the parent class method. Two methods are considered having same signature when their return type , method name, count and type of arguments are same.

Example For Java Method overriding:

class Bird{
   public void fly()
   {
      System.out.println("Bird is flying");
   }
}
class Parrot extends Bird{
   public void fly(){
      System.out.println("Parrot is flying");
   }
   public static void main( String args[]) {
      Parrot obj = new Parrot();
      obj.fly();
   }
}

class Bird{

public void fly()

{

System.out.println("Bird is flying");

}

class Parrot extends Bird{

public void fly(){

System.out.println("Parrot is flying");

}

public static void main( String args[]) {

Parrot obj = new Parrot();

obj.fly();

}

Output:

Parrot is flying

The overridden method must have the same signature as that of the parent class method.
