// A Simple Java program to demonstrate

// method overriding in java

  

// Base Class

class Parent {

    void show()

    {

        System.out.println("Parent's show()");

    }

}

  

// Inherited class

class Child extends Parent {

    // This method overrides show() of Parent

    @Override

    void show()

    {

        System.out.println("Child's show()");

    }

}

  

// Driver class

class Main {

    public static void main(String[] args)

    {

        // If a Parent type reference refers

        // to a Parent object, then Parent's

        // show is called

        Parent obj1 = new Parent();

        obj1.show();

  

        // If a Parent type reference refers

        // to a Child object Child's show()

        // is called. This is called RUN TIME

        // POLYMORPHISM - Interview question

        Parent obj2 = new Child();

        obj2.show();

    }

}







Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class. 

Method OverLoading

Method OverLoading

Duplicate/Same  method names used or called multiple times with different arguments.

---> Sample Program

package programs;

public class MethodOverloading {

// method

public void method1(int a) {

System.out.println(a);

}

// method

public void method1(String a) {

System.out.println(a);

}

public static void main(String[] args) {

// TODO Auto-generated method stub

// creating object for MethodOverloading

MethodOverloading obj = new MethodOverloading();

    obj.method1(10);

    obj.method1("test");

}

}

i.e

i.argument count should be different.

ii.argument data type should be different.
