I get exception when using Thread.sleep(x) or wait()

Question

I have tried to delay - or put to sleep - my Java program, but an error occurs.

I'm unable to use Thread.sleep(x) or wait(). The same error message appears:

unreported exception java.lang.InterruptedException; must be caught or declared to be thrown.

Is there any step required before using the Thread.sleep() or wait() methods?

Answer 1

You have a lot of studying leading you. From compiler errors throughout exception handling, threading and thread checks. But this will do what you require:

try {

    Thread.sleep(1000);                 //1000 milliseconds is one second.

} catch(InterruptedException ex) {

    Thread.currentThread().interrupt();

}
