Catch exception for Executor, thread pool

问题

For one thread, I catch the uncaught exception via below code segments. However, for ExecutorService executor = Executors.newFixedThreadPool(10);, how can I catch uncaught exception?

Thread.UncaughtExceptionHandler h = new Thread.UncaughtExceptionHandler() {
    public void uncaughtException(Thread th, Throwable ex) {
        System.out.println("Uncaught exception: " + ex);
    }
};

You can use the overload of the method newFixedThreadPool, which accepts a ThreadFactory:

Thread.UncaughtExceptionHandler eh = ...;
ThreadFactory factory = r -> {
    Thread t = new Thread(r);
    t.setUncaughtExceptionHandler(eh);
    return t;
};
ExecutorService executor = Executors.newFixedThreadPool(10, factory);
