sleep method

[Lalit mishra]

Thread.sleep(1000);
throws interrupted Exception
how can the thread be interrupted both programmatically and by user input ???(please give an example)

public class Javier {
public static void main(String[] args) {
Thread t = new Thread(new Runnable() {
public void run() {

/* An infinite loop that attemps to display a message every
* two seconds (this is not a warranty) */
while (true) {
try {
System.out.println("Hi this Child Thread: Hello every two seconds");
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
e.getMessage();
}

}

}
});

t.start();



/* An infinite loope that attemps to display a message every half a
* second (this is also not a warranty) */
while (true) {
try {
System.out.println("Hi this is Father Thread: Hello every half second");
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
e.getMessage();
}
}


//This is never reachead unless there's an exception



}
}


In the previous code I've created two threads. The one invoked by the JVM and a child Thread.

The Main Thread creates another child that will attemp to display a message every two seconds. And the Main Thread itself go to sleep every half a second and once is in the state of "runnable" It will display the message.

Interrupting Threads by user input requieres more code and can be done via a Graphical User Interface.
