Beginner in Java - need some help

[ea09530]

:confused:hello I have prepare to codes:
1) a timer that returns every sec the current date
2) A simple program that returns some infos
What I want to do (and I cant) is:
every sec that the date is returned from prog 1, to return also the infos of prog 2

Prog 1
----------------------------
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.Timer;

public class TimerTest
{
public static void main(String[] args)
{
ActionListener listener = new TimePrinter();
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(now);
Toolkit.getDefaultToolkit().beep();

}
}

Nothing is returned: both your actionPerformed( ... ) method as well as your main( ... ) method in your EmployeeProject3 class are void. Why not simpy add the following to your actionPerformed( ... ) method?

EmployeeProject3.main(null);

that way not just the current time is printed with a beep but the other class is run as well.

kind regards,

Jos

hi,
your 1st code is corrected in one postion:
JOptionPane.showMessageDialog(null, "Quit program?");
changed into :
JOptionPane.showMessageDialog(this, "Quit program?");

Sorry,I misunderstood you.
The following is my reply after understanding your meaning?
I hope it can help you.
