Call while (!iscomplete) multiple times while running the application; Blocking threads, causing thread resource consumption to be high. Modify the implementation method to reduce resource consumption

while (!iscomplete) {

try {

Thread.Sleep (100);
} catch (Interruptedexception e) {
TODO auto-generated Catch block
LOG.E (e);
}
Continue
