Write a Java program to sleep a thread

The Java code demonstrates the use of the Thread.sleep() method to pause the execution of the current thread for a specified duration. In the ThreadSleep class, the main method prints "Before Sleep" to the console. Then, it tries to sleep the main thread for 3 seconds using Thread.sleep(3000).

The Thread.sleep() method throws an InterruptedException when the current thread is interrupted while sleeping. In this case, the catch block will print the stack trace of the InterruptedException, but since the interruption is not explicitly handled in this code, the main thread will continue its execution after the catch block. After the sleep period, the code resumes its execution, and "After Sleep" is printed to the console.

Source Code

public class ThreadSleep
{
	public static void main(String[] args)
	{
		System.out.println("Before Sleep");
 
		try {
			Thread.sleep(3000); // Sleep for 3 seconds
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
 
		System.out.println("After Sleep");
	}
}

Output

Before Sleep
After Sleep
