Question

HI.
I want a function in java that automatically called.

for example wen we use Time class like blew

the actionperformerd() function call every 1second.

Timer time = new Time(10,this);
.
.
.
public void actionperformed()
{
        timer.run;
        //i want move a pic every 1millisecond.
}

my problem is that Timer class only accept int value and it’s minimum
value is 1 second and i want call actionperformed every 1 millisecond.

Answer 1

Java Timer accepts milliseconds in parameters. So you can do

new Timer().schedule(new TimerTask() {
public void run()  {
  // do stuff
}
}, 1, 1);

But to have real-time functionality with milliseconds precision you may need to switch to C.
