2. Write a program that creates three different classes in three different packages and access them from default package. All the three packages should be at the same level.

//* save as s file 1 Class1.java*/fi/*

package Pack1;

public class Class1

{

    public void print()

    {

        System.out.println("\npack 1 class 1");

    }

}

-------------------------------------------------------------------

/* save as a file 2 Class2.java */

package Pack2;

public class Class2

{

    public void print()

    {

        System.out.println("\npack 2 class 2");

    }

}

-------------------------------------------------------------------

/* save as a file 3 Class3.java */

package Pack3;

public class Class3

{

    public void print()

    {

        System.out.println("\npack 3 class 3");

    }

}

-------------------------------------------------------------------

/* save as a file 4 Program2.java */

package pack;

 

 import Pack1.*;

 import Pack2.*;

 import Pack3.*;

 

 public class Program2

 {

     public static void main(String args[])

     {

        Class1 c1 = new Class1();

        Class2 c2 = new Class2();

        Class3 c3 = new Class3();

       

        c1.print();

        c2.print();

        c3.print();

     }

 }
