Java Practices->Handle InterruptedException

Java Practices->Handle InterruptedException

In multi-threaded code, threads can often block; the thread pauses execution until some external condition is met, such as :

• a lock is released
• another thread completes an operation
• some I/O operation completes
• and so on...

Threads can be interrupted. An interrupt asks a thread to stop what it's doing in an orderly fashion. However, the exact response to the interrupt depends on the thread's state, and how the thread is implemented:

if the thread is currently blocking     stop blocking early    throw InterruptedException  else thread is doing real work    thread's interrupted status is set to true    if thread polls isInterrupted() periodically      (which is preferred)      orderly cleanup and stop execution      throw InterruptedException    else       regular execution continues
