Java Tutorial: Java Threads (Interrupting a Thread | Java thread interrupt)

DisplayThread.java

/*
 * Example of interrupting a thread that stops
 * working.
 * 
 * In this example, after interrupting the thread, we
 * are propagating it, so it will stop working. If we
 * don't want to stop the thread, we can handle it where
 * sleep() or wait() method is invoked.
