========================================================

package com.test.sample2;

//import com.test.sample1.methodB;

public class HarryPotter { public void notMyName() { System.out.println("Harry Potter is not my name."); //Lama LastName = new Lama();----->this will not work because class Lama in same1 is default //LastName.methodB(); } public static void main(String[] args) { //HarryPotter NoMyName = new HarryPotter(); //NoMyName.notMyname();

}

Output Dhawa is my first name. Harry Potter is not my name.
