Timer function prob

hi..
I am using Timer in my program to continuosly draw some circles after a small delay....but even if i give delay parameter as 1 millisecond..i draws circle after 10 ms...and bcoz of that whole proc works slow..is there any better way to do this or what is prob with Timer??

The Timer is not accurate enough to distinguish between resolutions of 1ms (I think it has more to do with the OS than the java Timer function though).  Anyways, you cannot rely on a Timer or Sleep function to accurately distinguish resolutions that small.

and if you could, the Timer would lock the system :-(

Try storing the System.currentTimeMillis() value at the end of the timer function, then drawing that number of circles next time the Timer fires...  bit of a hack, but you will get one circle per ms ;-)

ie:

draw ( System.currentTimeMillis() - oldTime ) circles
then set oldTime = System.currentTimeMillis() ;

sorry for late reply..but TimYates i didnt get ur solution...
see tihs is my code in Timer funciotn

speed=1;

myTimer=new Timer(speed,this) ;
      myTimer.start();

///in actionPerformed()

if (e.getSource() == myTimer)
   {
drawCircle(0);
if(i%2==0 )
 drawCircle(1);
if(i%4==0 )
drawCircle(2);
if(i%7==0 )
drawCircle(3);
i++;
  }
}

by tihs i want to draw 4 circles pixel by pixel with different speeds...and i want to draw first circle with speed 1ms...like when 1st circle completes 2 circles...2nd circle circle shud complete one round..like this...
but all this shud happen with speed given by 'speed' variable..so it is possible with System.currentTimeMillis()???
plz reply..

long oldTime = -1 ;

speed = 1 ;

myTimer=new Timer(speed,this) ;
      myTimer.start();

///in actionPerformed()

if (e.getSource() == myTimer)
{
  if( oldTime != -1 )
  {
    for( int cnt = oldTime ; cnt < System.currentTimeMillis() ; cnt++ )
    {
      drawCircle(0);
      if(i%2==0 )
        drawCircle(1);
      if(i%4==0 )
        drawCircle(2);
      if(i%7==0 )
        drawCircle(3);
      i++;
    }
  }
  oldTime = System.currentTimeMillis() ;
}

Would draw the correct number of circles...

If it took ages to get back to the function, it would draw lots...

You may want to rethink your idea though....one circle per ms is just a bit too quick... :-(
