Java Timer.Schedule (infiniti loop) stop running

Question

I have the follow problem: i'm writing an chat bot in java and i want to call a method even x minutes. So i read an "Timer.Schedule" is what i need. So i write the following method:

public function timerMethod()
{
    int time = 10;

    ...

    new java.util.Timer().schedule(
        new java.util.TimerTask() {
            @Override
            public void run() {
                timerMethod();
            }
        }, 1000 * 60 * time // 1MSec * 1Sec * xMin
    );
}

At the beginning the loop works fine but after a few hours (i think it's after 10-15 hours) the loop dont work anymore... I dont know why i dont work and dont get any error message :(

Can someone help me pleace???

Answer 1

So you want code to run for x minutes, correct?

If so, convert the time you want the code to run for into milliseconds like this : 1 minute = 60000 ms. There is a method called System.currentTimeMillis(), this will return a value of miliseconds from the EPOCH date (Jan 1, 1970).

You can use a while loop like this:

`

int msTime = 60000; //1 Minute = 60000 MS
int doUntil = ms + System.currentTimeMillis(); //1 minute
while(System.currentTimeMillis() != doUntil)
{
   //Code here
   System.out.println(¨Hello World¨); //This will print Ḧello World for 60000ms

}
