Java is a popular, object-oriented programming language used to build reliable and scalable applications. It follows the principle “Write Once, Run Anywhere”, allowing Java programs to run on different platforms using the Java Virtual Machine (JVM).
Java provides important features such as OOP, exception handling, multithreading, collections, and security. It is widely used for web applications, enterprise software, Android development, and backend systems. Frameworks like Spring and Spring Boot make Java even more powerful for developing modern applications and REST APIs.
