Handling InterruptedException in Java

Question

What is the difference between the following ways of handling InterruptedException? What is the best way to do it?

try{
 //...
} catch(Interrupt         


        

Answer 1

I just wanted to add one last option to what most people and articles mention. As mR_fr0g has stated, it's important to handle the interrupt correctly either by:

• Propagating the InterruptException

• Restore Interrupt state on Thread

Or additionally:

• Custom handling of Interrupt

There is nothing wrong with handling the interrupt in a custom way depending on your circumstances. As an interrupt is a request for termination, as opposed to a forceful command, it is perfectly valid to complete additional work to allow the application to handle the request gracefully. For example, if a Thread is Sleeping, waiting on IO or a hardware response, when it receives the Interrupt, then it is perfectly valid to gracefully close any connections before terminating the thread.

I highly recommend understanding the topic, but this article is a good source of information: http://www.ibm.com/developerworks/java/library/j-jtp05236/
