CopyOnWriteArrayList is a class in Java that is part of the `java.util.concurrent` package. It is a thread-safe variant of the `ArrayList` class. The key feature of `CopyOnWriteArrayList` is that it provides a way to achieve thread-safety without the need for explicit synchronization. Here's how CopyOnWriteArrayList works: 1. Copy-On-Write Strategy: When an element is added, modified, or removed from the `CopyOnWriteArrayList`, a new copy of the underlying array is created. This new copy is then modified with the required changes. This strategy ensures that the original array remains unchanged, providing a consistent view of the data for any currently iterating threads. 2. Reads are Non-blocking: The reading operations (such as `get` and `iterator`) operate on the current underlying array without acquiring any locks. This makes the read operations very fast and suitable for situations where reads are more frequent than writes. 3. Iterators are Snapshot Iterators: The iterator...

In this post, we will learn about Executor Framework in Java and this helps in Simplifying Concurrent Programming, with Examples Introduction Concurrent programming plays a vital role in developing efficient and responsive Java applications. However, managing threads manually can be complex and error-prone. To simplify concurrent programming, Java provides the Executor Framework as part of the java.util.concurrent package. In this blog post, we will explore the Executor Framework, its benefits, and provide working examples to help you leverage its power in your Java projects. 1. Understanding the Executor Framework The Executor Framework is built on the concept of thread pools, which manage a pool of worker threads and execute tasks concurrently. It decouples the task submission from the thread management, allowing developers to focus on the logic of their tasks while leaving the thread management to the framework. 2. Key Components of the Executor Framework a. Executor Interface: It r...
