Introduction This is a continuation post on the exception handling strategies in the threads in Java. For Introduction, please read this post The second post is available here This post addresses the problem statement "How to use the exception handlers in the threads spawned by the Executor Service in Java?" Not all times, we will be using Thread  classes to run our threads because we have to manage a lot of the underlying logic for managing threads. There is ExecutorService in Java which comes to the rescue for the above problem. In the previous posts, we have discussed on how to handle the exceptions in plain threads. However, when using executor service, we do not create / manage threads, so how do we handle exception in this case. We have a ThreadFactory   as an argument which can be used to customize the way threads are created for use within the ExecutorService . The below snippet of code leverages this feature to illustrate the exception handling, wherein we create a
