How do I make a delay in Java?

To make a delay in Java, you can use the Thread.sleep method which will pause the current thread for a specified number of milliseconds. Here's an example:

try {
    Thread.sleep(1000); // delay for 1 second
} catch (InterruptedException e) {
    e.printStackTrace();
}

Note that the Thread.sleep method can throw an InterruptedException, so it's a good idea to include a try-catch block to handle this exception.

Alternatively, you can use the java.util.concurrent.TimeUnit class to specify the delay time in a more readable format, like this:

try {
    TimeUnit.SECONDS.sleep(1); // delay for 1 second
} catch (InterruptedException e) {
    e.printStackTrace();
}

This can be useful if you want to specify the delay time in terms of minutes, hours, or days, rather than in milliseconds.
