How to do it...

Follow these steps to implement the example:

1. Create a class named Flag with a public Boolean attribute named flag initialized to the true value:

        public class Flag {           public boolean flag=true;         }

2. Create a class named VolatileFlag with a public Boolean attribute named flag initialized to the true value. We add the volatile modifier to the declaration of this attribute:

        public class VolatileFlag {           public volatile boolean flag=true;         }

3. Create a class named Task and specify that it implements the Runnable interface. It has a private Flag attribute and a constructor to initialize it:

        public class Task implements Runnable {           private Flag flag;           public Task(Flag flag) {             this.flag = flag;           }
