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 […]
In Java, multithreading allows concurrent execution of multiple threads, which can enhance performance and responsiveness in applications. However, concurrent execution introduces challenges regarding data consistency and integrity. To manage these challenges, Java provides several mechanisms, including atomic operations, volatile variables, and synchronized blocks. Here’s a breakdown of each: 1. Atomic Atomic operations are those that […]
Thread priority in Java determines the relative importance of a thread, which can influence the order in which threads are scheduled for execution by the JVM’s thread scheduler. Threads with higher priority are generally given preference over threads with lower priority when CPU resources are limited. Key Points about Thread Priority: Priority Levels: Each thread […]
Daemon threads in Java are special types of threads that run in the background and perform tasks such as garbage collection, monitoring, and other low-priority operations. They are typically used for service-like functions that the application doesn’t need to wait for when exiting. Unlike normal (non-daemon) threads, daemon threads do not prevent the JVM from […]
Parallelism and Concurrency are two concepts in computer science that are often confused but represent different approaches to handling tasks. Let’s break down the differences: 1. Concurrency: Definition: Concurrency refers to the ability of a system to handle multiple tasks by interleaving their execution. The tasks can start, run, and complete in overlapping time periods. […]
Java 17 and Java 18 introduced several new features and improvements, but because Java 17 is a Long-Term Support (LTS) release, it’s considered a more stable and supported version over a longer period than Java 18, which is a regular release with a shorter support cycle. Here’s a breakdown of significant changes in Java 17 […]

Java Versions and Release Dates: Version Release Date Key Features JDK 1.0 January 23, 1996 Initial version, basic features like applets JDK 1.1 February […]
Java has undergone significant changes from Java 9 to Java 22+, with each version introducing new features, performance improvements, and API updates. Here’s a comprehensive overview of the essential features introduced from Java 9 to Java 22. Java 9 (Released September 2017) Module System (Project Jigsaw): Introduced the Java Platform Module System (JPMS), which modularizes […]
Java 8, released in March 2014, is one of the most significant updates in the history of Java, introducing major changes that revolutionized the way developers write code. These new features made Java more expressive, concise, and capable of handling modern programming paradigms like functional programming. Here’s an overview of the key features introduced in […]
What are Java Streams? Java Streams are a powerful and modern API introduced in Java 8 as part of the Java Streams API under the java.util.stream package. Streams provide a declarative way to process sequences of elements (such as collections or arrays) in a functional programming style. Instead of manually iterating over collections with loops, […]
