How Can I Synchronize Completion of Concurrent Tasks in Java?

How to Concurrently Execute Tasks and Synchronize Completion in Java

When multiple tasks need to execute concurrently in Java, threading is a common technique. However, it's often necessary to synchronize these threads to ensure their completion before proceeding. This question delves into a scenario where multiple threads are created and executed in a loop, and how to pause the main thread until all of them have finished.

Solution: Utilizing Thread.join()

To achieve synchronized completion, you can employ the join() method. By placing the threads in an array and subsequently starting them, you can easily suspend the main thread using a loop that iterates through the array:

<code class="java">for(i = 0; i < threads.length; i++)
  threads[i].join();</code>
Copy after login

The join() operation for each thread blocks until that thread completes. Although the threads may finish in a sequence that differs from the order in which they were joined, this does not affect the intended outcome. Once the loop concludes, all threads will have finished their execution, ensuring that the main thread can continue.
