Write a program that creates illustrates different levels of protection in classes/subclasses belonging to same package or different packages.

Write a program that creates illustrates different levels of protection in classes/subclasses belonging to same package or different packages.

Program:

Code of program1 in Package:

package Protection;

public class Protectionpackage {

    public String str1 = "I am Public";

    private String str2 = "I am Private";

    protected String str3 = "I am protected";

    public void readString() {

        System.out.println("Public String : " + str1);

        System.out.println("Private String : " + str2);

        System.out.println("Protected String : " + str3);

    }

}

Code of program2 in same Package:

package Protection;

public class Protection2package extends Protectionpackage {

    public void readStringextends() {

        System.out.println("Public String accessible within package : " + str1);

        System.out.println("Private String is not accessible within package");

        System.out.println("Protected String accessible within package : " + str3);

    }

}

Code of program outside the package:

import Protection.*;

public interface Protection {

    public static void main(String args[]) {

        Protection2package p2 = new Protection2package();

        Protectionpackage p1 = new Protectionpackage();

        p1.readString();

        p2.readStringextends();

        System.out.println("Public string accessible outside package :" + p1.str1);

        System.out.println("Private string is not accessible outside package");

        System.out.println("Protected string is not accessible outside package");

    }

}
