how to properly sleep in loop

Question

I have a loop who's job is to act as a blocking command, execute a shell command once every second. Java warns about "sleeping in loop". Here is the code:

    while (!Shell.silentShellCommand(stringCommand).contains("Device detected")) {
        try {
            Thread.sleep(1000);
        } catch (InterruptedException ex) {
            log.errorHandler(ex);
        }
    }

Surely there is a better way to do this. I just don't know how. What would be the proper way to make a "blocking timer method"? I am using this to pause execution until the user does something.

Answer 1

Why not do something like this:

public void loopMethod(){
    if(!Shell.silentShellCommand(stringCommand).contains("Device detected")){
        try {
            Thread.sleep(1000);
        } catch(InterruptedException ex) {
            ex.printStackTrace();
        }
        loopMethod();
    }
}

And just call that method from a background thread. Would that work? I mean, it's still technically a loop, but it looks cleaner for some reason!
