I am getting the error, unreported exception InterruptedException; must be caught or declared to be thrown Thread.sleep(10);. I think I need to write a try and catch but I'm not sure how and where to put it.

import java.util.Date; import java.lang.*;

public class Factory { public static void main(String args[]) { // creates the message queue Channel queue = new Channel(); // Creates the producer and consumer threads and pass Thread producer = new Thread(new Producer(queue)); Thread consumer = new Thread(new Consumer(queue)); // start the threads producer.start(); consumer.start(); } }

class Channel {

private Date date;

public void send(Date message){ this.date = message; }

public Date receive() {

return date; }

}

class Producer implements Runnable {

private Channel queue; public Producer(Channel queue) { this.queue = queue; } public void run() { Date message;

while (true) { // nap for awhile Thread.sleep(10);

// produces an item and enter it into the buffer message = new Date(); System.out.println("Producer produced " + message); queue.send(message);

}

} }

class Consumer implements Runnable{ private Channel queue;

public Consumer(Channel queue) { this.queue = queue;

} public void run() { Date message;

while(true) { // nap for awhile Thread.sleep(10);

// consumes an item from the buffer message = queue.receive();

if (message != null) System.out.println("Consumer consumed " + message);

}

}

}
