Best practice for "DO Nothing" Strategy for InterruptedException.

 

     try {
             while (true) {
                Thread.sleep(2000);
             }
         }
         catch (InterruptedException swallowedTheException) {
             /* BAD PRACTICE */
         }

Instead re-interrupt the thread by calling interrupt() method. Because when the sleep() blocking method sniffs an interruption and throws InterruptedException, it clears the interrupted status.

     try {
             while (true) {
                 Thread.sleep(2000);
             }
         }
         catch (InterruptedException notSwallowedTheException) {
             // Restore the interrupted status
             Thread.currentThread().interrupt();
         }
