Java Multithreading Example: Counter and SleepyCounter Threads

import java.util.Random;

class Counter implements Runnable { private static int count = 0;

@Override
public void run() {
    for (int i = 0; i < 5; i++) {
        System.out.println('Counter: ' + count++);
        try {
            Thread.sleep(new Random().nextInt(1000));
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

}

class SleepyCounter implements Runnable { private static int count = 0;

@Override
public void run() {
    for (int i = 0; i < 5; i++) {
        System.out.println('SleepyCounter: ' + count++);
        try {
            Thread.sleep(new Random().nextInt(1000));
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

}

public class CounterApp { public static void main(String[] args) { Thread counterThread = new Thread(new Counter()); Thread sleepyCounterThread = new Thread(new SleepyCounter());

    counterThread.start();
    sleepyCounterThread.start();
}
