Hello I would like to implement multiple swing timers, each of which have a different function, but I cannot seem to separate the functions. I have one actionlistener and I cannot make another one. Please help.

I would like to implement multiple swing timersyes good idea, is possible
each of which have a different functionyes good idea, probably safer way
but I cannot seem to separate the functions. I have one actionlistener and I cannot make another onefrom ActionListener you can call Timer (I hope that we speak about java.swing.Timer, because there are also exists java.util.Timer) as 2nd parameter you put only Action (java.swing.Action)
nice idea, but without base (without your code)
much luck

here is my code. the actionListener would be one and the delayTime would be another one, but how would I call a timer from the actionlistener?
// The "FractionReaction" class.
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import com.games4j.webAPI.*;
public class FractionReaction extends Applet implements KeyListener, ActionListener
{
Timer timer, wait;
double waitTime;
int screen = 0, select = 1, delay, startBox = 0, time = 0;
double seconds;
Color sqcol = Color.blue;
boolean loggedIn;
// Place instance variables here
public void init ()
{
resize (300, 300);
//timer = new Timer (1, actionPerformed);
//wait = new Timer (1000, delayTime);
wait.start ();
waitTime = Math.random () * 999999000;
delay = (int) Math.round (waitTime);
loggedIn = Highscore.isLoggedIn (applet);
addKeyListener (this);
// Place the body of the initialization method here
} // init method
public void paint (Graphics g)
{
if (screen == 0)
{
if (!loggedIn)
{
g.drawString ("log in to be able to save highscores!!!", 10, 5);
}

}
if (screen == 1)
{

{

g.fillRect (100, 100, 100, 100);
//for (int i = 0; i < waitTime; i++);
}
else if (startBox == 1)
{
sqcol = Color.red;

g.fillRect (100, 100, 100, 100);
}

I'm sorry I still don't understand could you please elaborate a bit more On the actual timer part?
Mattox
Timer timer_1, timer_2;
timer_1 = new Timer(new TimerAction1());
timer_2 = new Timer(new TimerAction2());
//the 2 timers call different methods
//define the 2 methods
class TimerAction1 implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
//whatever you want the first timer to do
}
}
class TimerAction2 implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
//whatever you want Timer2 to do
}
}As far as using all the methods for the timer class I would have to see the code to help with that.

hmmm, how long you want to waiting
waitTime = Math.random () * 999999000;max value for timer is in mileseconds.... that's maybe more than 2month
you are put here some code sniped, that's out of context (for me),
again post here YOUR real code plus you have to DESCRIBE what you are really want to do....
