How do you cause a program to wait for a set amount of time?

Question

How do you make a program that waits for 3 seconds? I've heard about this:

obj.wait()

But I'm just wondering about the syntax and what to import?

`obj.wait()` is to wait until another thread calls `notify()`. Nothing directly to do with "waiting for X amount of time". — Steve Smith, Aug 08 '18 at 15:57

This will put your code to sleep for 3 seconds:

try{
Thread.sleep(3000);
} catch(InterruptedException e) {
 Thread.currentThread().interrupt();
}

You have to import `

java.util.concurrent.TimeUnit

`and the you can run:

TimeUnit.SECONDS.sleep(100);
