Java code speed improvement

Hi all may such a code cause lag of process?

while(true)
if(!connected) break;

As we see it checks for condition all the time. Would it be faster if I set small sleep in each iteration.

The code runs on Android GingerBread.

EDIT:

It waits for other Thread to finish and set variable Connected to false. Variable connected is used like lock. thread usually finds it true and waits to be false. then sets to true and only changes it at the end.

Solution

  • I think it would be better to add small sleep in your loop, to free processor resources for other processes, especially on one-core processor.
