If I want to delay something in java, how would I do it? I know in turing there is a delay (*) but Im not sure what it is for java.

I think you might be looking for sleep()

use this... put it in the same directory as your program... and in your program put "Delay.stop(int);" before whatever you want delayed.... just like in turing.

Our teacher taught us to use a useless for loop that runs like a million times Confused . I guess that works as well Twisted Evil

errrr not really, cuz you're delaying by the number of times your CPU can go through that for loop, so the slower comp you have, the longer delay you'll have.

This is far worse than using processes in Turing, and you know how bad that is. Unless, of course, you have a constant frame rate, but even then using the Thread.sleep() method is what you should be using.

code:
public static void delay (int millisecs)
    {
        try
        {
            Thread.currentThread ().sleep (millisecs);
        }
        catch (InterruptedException e)
        {
        }
    }

Note that you don't need to explicitly state that you're delaying currentThread(), Thread.sleep() should be sufficient, especially since you're probably only working with the default Thread.

code:
void delay_a_bit() {
  for (int i=0;i<1000000;++i) {
    int x = Math.sqrt (i * i);
  }
}
