Don't immediately yank out the batteries! Typically there are two answers to that question: <br/>1) Rethrow the InterruptedException from your method. This is usually the easiest and best approach. It is used by the new java.util.concurrent.* package [ <a href="http://java.sun.com/j2se/1.5.0/docs/api/java/util/concurrent/Semaphore.html#acquire()">http://java.sun.com[..]util/concurrent/Semaphore.html#acquire()</a> ], which explains why we are now constantly coming into contact with this exception. <br/>2) Catch it, set interrupted status, return. If you are running in a loop that calls code which may cause the exception, you should set the status back to being interrupted. For example: <br/><pre>while (!Thread.currentThread().isInterrupted()) {<br/> // do something<br/> try {<br/> TimeUnit.SECONDS.sleep(1000);<br/> } catch (InterruptedException e) {<br/> Thread.currentThread().interrupt();<br/> break;<br/> }<br/>}</pre>Remember the Law of the Sabotaged Doorbell - don't just ignore interruptions, manage them properly!<br/><br/>- <a href="http://www.javaspecialists.eu/archive/Issue146.html">http://www.javaspecialists.eu/archive/Issue146.html</a> <br/><br/>Another blog explain about InterruptedException - <a href="http://www.nurkiewicz.com/2014/05/interruptedexception-and-interrupting.html">http://www.nurkiewicz.com[..]terruptedexception-and-interrupting.html</a> <br/><br/><a href="http://ocpsoft.org/regex/how-to-interrupt-a-long-running-infinite-java-regular-expression">http://ocpsoft.org[..]running-infinite-java-regular-expression</a> <br/><br/><a href="http://praveer09.github.io/technology/2015/12/06/understanding-thread-interruption-in-java/">http://praveer09.github.io[..]derstanding-thread-interruption-in-java/</a> <br/><br/>How to Stop a Java Thread Without Using Thread.stop()? - <a href="https://4comprehension.com/how-to-stop-a-java-thread-without-using-thread-stop/">https://4comprehension.com[..]a-java-thread-without-using-thread-stop/</a> <br/><br/><script type="text/javascript"><!--google_ad_client = "pub-9426659565807829";google_ad_slot = "9359905831";google_ad_width = 728;google_ad_height = 15;//--></script><script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script> 2022-03-19T12:00:19Z
