//How to create Multiple class in java Program

import java.io.*;

// Class 1

// A Grand parent class in diamond

class GrandParent {

void fun() {

// Print statement to be executed when this method is called

System.out.println("Grandparent");

}

}

// Class 2

// First Parent class

class Parent1 extends GrandParent {

void fun() {

// Print statement to be executed when this method is called

System.out.println("Parent1");

}

}

// Class 3

// Second Parent Class

class Parent2 extends GrandParent {

void fun() {

// Print statement to be executed when this method is called

System.out.println("Parent2");

}

}

// Class 4

// Inheriting from multiple classes

class Test extends Parent1, Parent2 {

// Main driver method

public static void main(String args[]) {

// Creating object of this class i main() method

Test t = new Test();

// Now calling fun() method from its parent classes

// which will throw compilation error

t.fun();

}

}
