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.

yes good idea, is possible

each of which have a different function

yes good idea, probably safer way

but I cannot seem to separate the functions. I have one actionlistener and I cannot make another one

from 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?

        wait.start ();
        waitTime = Math.random () * 999999000;
        delay = (int) Math.round (waitTime);

        f.add(p);
        f.pack();
        f.setVisible(true);

        t.restart();
    }

    }

    @Override

        lGallons.setText(nf.format(d));

I'm sorry I still don't understand could you please elaborate a bit more On the actual timer part?

Edited 5 Years Ago by sirlink99: n/a

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....
