What are some examples of using ExecutorService in Java?

Can you explain what ExecutorService is in Java?

ExecutorService is an interface in Java that provides a higher-level replacement for managing threads. It simplifies the execution of asynchronous tasks.

What are some common use cases for ExecutorService?

Common use cases include managing a pool of threads for executing tasks concurrently, scheduling tasks, and handling asynchronous processing.

Can you give me a code example of using ExecutorService?

Sure! Here's a simple example:

ExecutorService executor = Executors.newFixedThreadPool(2);
executor.submit(() -> {
    System.out.println("Task 1");
});
executor.submit(() -> {
    System.out.println("Task 2");
});
executor.shutdown();

How do I handle exceptions in tasks submitted to ExecutorService?

You can handle exceptions by using a try-catch block within the task's run method or by using Future objects to retrieve exceptions after task completion.
