How do I add a delay in my program in Java?

You have a problem that you want to add a delay for a couple of seconds in you program. Here is an example for this problem.

public class DelayExample 
{    
    public static void main(String[] args)
    {
        // This program demonstrate how to add a delay in our application.
        for (int i = 0; i < 10; i++)
        {
            // Print the value of i
            System.out.println("i = " + i);
            
            try
            {
                // Using Thread.sleep() we can add delay in our application in
                // a millisecond time. For the example below the program will 
                // take a deep breath for one second before continue to print
                // the next value of the loop.
                Thread.sleep(1000);
                
                // The Thread.sleep() need to be executed inside a try-catch
                // block and we need to catch the InterruptedException.
            } catch (InterruptedException ie)
            {
                ie.printStackTrace();
            }
        }
    }
}
