multithreading - Java re-doing a piece of code ... using threads

Question

Let's say I have this code:

public class helloworld
{
        public static void main(String args[])
        {

           System.out.println("Hello World!");

        }
}

Using threads, is there a way I can make Hello world echo continuously every 5 seconds?

Answer 1

This version repeats the hello world message continuously, while allowing the user to terminate the message-writing thread:

public class HelloWorld {

    public static void main(String[] args) throws Exception {
        Thread thread = new Thread(new Runnable() {

            public void run() {
                try {
                    while (!Thread.currentThread().isInterrupted()) {
                        Thread.sleep(5000);
                        System.out.println("Hello World!");
                    }
                } catch (InterruptedException e) {
                    Thread.currentThread().interrupt();
                }
            }
        });
        thread.start();
        System.out.println("press any key to quit");
        System.in.read();
        thread.interrupt();
    }
}
