The newCachedThreadPool() method in Java is a factory method provided by the Executors class that creates a type of ExecutorService with a dynamically growing and shrinking pool of threads. Here’s an overview of how it works and when it’s useful: What is newCachedThreadPool()? newCachedThreadPool() creates a thread pool that can dynamically allocate new threads as […]

Virtual Threads in Java 21 (Project Loom) Java 21 introduces Virtual Threads as a standard feature, marking one of the most significant changes to Java’s concurrency model since the introduction of threads. Virtual Threads are part of Project Loom, an initiative aimed at improving Java’s concurrency handling, making it more lightweight, scalable, and developer-friendly. What […]

ThreadLocal and InheritableThreadLocal are two important classes in Java that provide a way to store data specific to a thread. They are widely used in multithreading environments to ensure that each thread has its own independent copy of variables. Let’s break down both concepts: 1. ThreadLocal in Java Definition: ThreadLocal provides thread-local variables. Each thread […]

Java Multithreading is a process where multiple threads are executed simultaneously in a Java program. A thread is a lightweight subprocess, and multithreading allows concurrent execution of two or more parts of a program for maximum utilization of CPU resources. Why Use Multithreading? Improved Performance: It allows better CPU utilization, especially when tasks can be […]

Virtual Threads in Java and Promises in JavaScript are both mechanisms designed to handle concurrency and asynchronous tasks, but they operate very differently and serve different purposes within their respective languages. Let’s break down the similarities and differences: What are Java Virtual Threads? Virtual Threads, introduced in Java 21, are lightweight, JVM-managed threads that allow […]

ExecutorService is a part of the Java Concurrency framework that provides a higher-level mechanism for managing and controlling threads. It simplifies the process of managing thread execution, especially in multi-threaded applications. Here are some basic uses and key features of ExecutorService: 1. Creating Thread Pools ExecutorService allows you to create a pool of threads, which […]

In Java, the ExecutorService provides a way to manage threads in a pool rather than creating new threads directly. Thread pools are more efficient for managing multiple concurrent tasks, especially when you need to handle a large number of tasks or need fine-grained control over concurrency. The ExecutorService framework provides several types of thread pools, […]

The SingleThreadExecutor in Java is a part of the java.util.concurrent package and provides a way to create a thread pool that consists of only one thread. It ensures that tasks are executed sequentially (one after another) in the order they are submitted. If additional tasks are submitted while a task is running, they are placed […]

A race condition in Java (and in computing in general) occurs when two or more threads (or processes) access shared resources (such as variables, objects, or memory) concurrently, and the final outcome or behavior depends on the order in which the threads execute. If the threads execute in an unpredictable or incorrect order, the outcome […]
