Accessing Private data of another class[Extreme logic program]

you all know very well java does'nt allow you to access private variables and methods outside the class.However ther is some loopholes in java "TO DO THIS".

consider a sample class:

private.java



public class privatedata {
    private void message()
    {
        System.out.print("This message was derived from private data");
    }
    private void message(String data)
    {
        System.out.print("your message is"+data);
    }

}

now am accessing private method from outside class "LETS ROCKZZZZ"

import java.lang.reflect.*;
public class accssingprivatedata {
    public static void main(String args[])
    {
        try
        {
            Class c=Class.forName("privatedata");
            Object obj=c.newInstance();
            Method m=c.getDeclaredMethod("message", null);
            m.setAccessible(true);
            m.invoke(obj, null);
        }
        catch (Exception e) {
            // TODO: handle exception
        }
       
    }

}
