How do you handle exceptions in multithreaded environment?

How do you handle exceptions in multithreaded environment?

We simply placed a try/catch block around the start() method. After all, start() instantiates the secondary thread and calls its run() method and the use of try/catch is the natural way of dealing with exceptions. If the code in run() throws any exceptions we should be able to catch them.

What do you mean by handling exceptions during multithreading?

Traditional exception handling We deal with exceptions in a single thread by throwing them up, or by try ing In the multithreaded environment, the main thread can’t handle the exception thrown by the child thread.

Can Run method throw exception?

Yes, because any exception you throw in run method will be carefully ignored by JVM. Thus, throwing it there is probably a mistake (unless you have specific exception handler for the thread, see the docs about that).

Is it possible to use multi-threaded exception handling in Java?

Java is currently being considered as a platform for deploying mission-critical applications. Multithreaded exception handling is a reality in this environment. While much documentation exists on the virtues of using threads of execution and exceptions in Java, there is little documentation on how to integrate the two.

How to manage concurrent threads of execution in Java?

The core problem that must be dealt with is how to manage concurrent threads of execution when one, or many, of those threads may terminate abnormally. We need a way to be notified of any errors occurring on secondary threads, and a solution that enables us to terminate gracefully while optionally preserving object state.

Can a secondary thread terminate due to an exception?

A key point to note is the primary thread must be able to determine the status of the secondary thread. This can be difficult particularly when the secondary thread may terminate due to an exception. What if you were writing a mission-critical application? How would you report failures in secondary threads to the calling code?

Can a single threaded application handle multiple threads?

Doing so in single-threaded applications is challenging enough without introducing multiple threads of execution. The core problem that must be dealt with is how to manage concurrent threads of execution when one, or many, of those threads may terminate abnormally.
