Is There a Built-in Concurrent List with Indexed Access in Java\'s JDK?

Can I Utilize a Concurrent List with Indexed Access in Java's JDK?

Envision a scenario where you require a concurrent List implementation which allows access to elements through their index. Does the Java Development Kit (JDK) offer any built-in classes or factory methods to facilitate this?

ConcurrentLinkedQueue: A Solution for Indexed Access

While the JDK lacks an explicit concurrent List with indexed access, you can leverage the java.util.concurrent.ConcurrentLinkedQueue class for this purpose. Granted, it doesn't natively provide index-based access, but it maintains the order of insertion, which is a critical characteristic of Lists. Its Iterable implementation allows you to iterate over its contents using the enhanced for syntax:

Queue<String> globalQueue = new ConcurrentLinkedQueue<String>();

// Multiple threads can safely call globalQueue.add()...

for (String href : globalQueue) {
    // Perform operations on href
}

This solution provides a workaround for the absence of a concurrent List with indexed access in the JDK.
