Spring Data JPA is a powerful and user-friendly framework that simplifies data access and persistence in Java applications using the Java Persistence API (JPA). It is part of the larger Spring Data family, which aims to provide consistent data access solutions across various data stores. What is ORM? ORM stands for Object-Relational Mapping. It is […]
Garbage collection is an essential process in modern programming languages, including Java, to manage memory dynamically and automatically deallocate objects that are no longer needed. The Garbage Collector (GC) is a critical component of the Java Virtual Machine (JVM) responsible for reclaiming memory occupied by unused objects, thereby preventing memory leaks and optimizing memory usage.
In this page, we delve into the intricate workings of Java Memory-Model . Whether you’re a beginner or an experienced Java developer, join us on this journey to unravel the complexities of Java Memory-Model. In the realm of programming, memory management refers to the dynamic allocation and deallocation of objects. In Java, this responsibility is
Welcome to our comprehensive guide on Multithreading and Synchronization! In this page, we will delve into the fascinating world of concurrent programming and explore the essential concepts, techniques, and best practices for effectively managing multiple threads in your applications. Multithreading is a powerful paradigm that allows programs to execute multiple tasks concurrently, thereby utilizing the

A semaphore controls access to a shared resource through the use of a counter. What the counter is counting are permits that allow access to the shared resource. Thus, to access the resource, a thread must be granted a permit from the semaphore. Synchronized allows only one thread of execution to access the resource at the same time. Semaphore
The lock interface is one of the most used interfaces in Java. Lock interface is available in the Java.util.concurrent.locks package which we use as a thread synchronization mechanism, i.e., similar to synchronized blocks. It is more flexible and provides more options in comparison to the synchronized block. It allows us to gain the benefit of fine-grained locking without having
Java 7 introduced the fork/join framework. It is among the simplest and most effective design techniques for obtaining good parallel performance. Fork/join algorithms are parallel versions of familiar divide−and−conquer algorithms. The fork operation starts a new parallel fork/join subtask. The join operation causes the current task not to proceed until the forked subtask has completed.

Java concurrency API includes the executor framework since java 5 to improve the performance of concurrent applications with a lot of concurrent tasks. It is a mechanism that allows you to separate thread creation and management for the implementation of concurrent tasks. You don’t have to worry about the creation and management of threads, only

Synchronization is the coordination of two or more tasks to get the desired results. We have two kinds of synchronization: synchronization helps you avoid some errors you can have with concurrent tasks but it introduces some overhead. You have to calculate very carefully the number of tasks, which can be performed independently without intercommunication in
