Re: How to make a Java class only visible inside the package & not visible to other packages?

Thank you all. I have taken Mark Space's idea and played on Eclipse. He
is right. Following is my program. There are three packages: package
one, package two and default package.

<package one>
<People.java>
package one;

public interface People
{
     String getName();
}
</Peopel.java>
</package one>

<package two>
<Person.java>
package two;

import one.People;

class Person implements People
{
     private String _name;

     public Person()
     {
         _name = "Tom";
     }

     public String getName()
     {
         return _name;
     }
}
</Person.java>

<PeopleProxy>
package two;

import one.People;

public class PeopleProxy
{
     static public People getPeople() { return new Person(); }
}
</PeopleProxy>
</package two>

<package default>
<HelloWorld.java>
import one.People;
import two.PeopleProxy;

public class HelloWorld
{

    public static void main( String[] args )
    {
        People p = PeopleProxy.getPeople();

             System.out.println(p.getName()); //Successfully print out
"Tom"

    }
}
</HelloWorld.java>
</package default>
