I am trying to access variables in another package in java, I tried some code:

The first package contains two classes, this is the first one

package encapsuation;

import s2.foo;



public class Encapsulation {



    public static void main(String args) {

        s1 a = new s1();

        a.age = 21;

        a.name = "ahmed";



        a.print();

        foo.print();

    }



}

The second one, this is what I need to access in the class of the second package.

package encapsuation;



public class s1 {

    public  static String name;

    public static int age;



    public static void print()

    {

        System.out.println(name + " " + age);    

    }

}

The second package contain one class

package s2;

import encapsuation.s1;



public class foo{



    public static void print()

    {

        System.out.println(s1.name + " " + s1.age);    

    }



}

Is what I am trying correct?

And why I cannot access the variables in class of the second package in the class "public class foo" but can access them in the method print only?

You can do something like this:

public class foo{

    String s = s1.name; 

    public static void print()

    {

        System.out.println(s1.name + " " + s1.age);    

    }



}

You have declared your variables as public static in class s1,

public class s1 {

    public static String name;

    public static int age;

....

}

public means it can be accessed anywhere, and static means it can be accessed by just class name s1

So no matter, whether in same package or any other package, you can always access those variables. So for example you can do something like this in foo class which is present in some other package,

public class foo{



    static {

        s1.name = "new name";

        s1.age = 555;

    }



    public static void print()

    {

        System.out.println(s1.name + " " + s1.age);    

    }



}
