Problem to access data when a class calls another class

Hello everybody,
I am new to java and I can not finish this exercise.

I have a timer (Prog1) that calls an Employee Report (Prog2).
The forum gave me the answer how Prog1 can can call Prog2.
For every tick of the timer (Prog1), how can I double the value of the field basic_salary (Prog2)????
Any help/advice/hints to this would be valuable to me becuase I dont know how to fight it. Thanks. Michael

Code:

---

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.Timer;
// to resolve conflict with java.util.Timer

public class TimerTest
{ 
  public static void main(String[] args)
  { 
      ActionListener listener = new TimePrinter();

      // construct a timer that calls the listener
      // once every 10 seconds
      Timer t = new Timer(1000, listener);
      t.start();
      JOptionPane.showMessageDialog(null, "Quit program?");
      System.exit(0);
  }
}

class TimePrinter implements ActionListener
{ 
  public void actionPerformed(ActionEvent event)
  { 
        Date now = new Date();
        System.out.println("Title current: " + now);
    Toolkit.getDefaultToolkit().beep();
    EmployeeProject3.main(null);
  }
}
