Run a code on exit

Sometimes you would like to run a code at close point of your application. The implementing is very easy and is just by adding a ShutdownHook to your application.

hier is the example:

public class RunAtEnd {     public static void main(final String[] args) {         System.out.println("Starting the program");         Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {             @Override             public void run() {                 System.out.println("You've closed your program");             }         }));                  System.out.print("Waiting 5 seconds ");         for (int i = 0; i < 5; i ++) {             System.out.print(".");             try {                 Thread.sleep(1000);             }             catch (final InterruptedException e) {                 e.printStackTrace();             }         }         System.out.println("");     } }
