Java

Definition

Java is a robust, platform-independent, object-oriented programming language developed by Sun Microsystems (now owned by Oracle). It is designed to have minimal implementation dependencies, making it suitable for developing applications that can run on any device or operating system that supports Java. Java programs are compiled into bytecode, which can run on Java Virtual Machines (JVMs), ensuring portability across different platforms. Java is renowned for its security features, including runtime checking for data integrity and memory management. It is widely used in enterprise-level applications, web development, mobile apps (Android), and large-scale systems due to its scalability, performance, and extensive libraries and frameworks.
