Java is a high-level, class-based, object-oriented programming language designed to have as few implementation dependencies as possible. Governed by Oracle, it follows the "Write Once, Run Anywhere" (WORA) principle, allowing developers to compile code once and execute it across any platform or device using the Java Virtual Machine (JVM).Why Java is Widely UsedPlatform Independence: Compiled Java code translates into intermediate bytecode, which can be interpreted by the JVM on any operating system (Windows, Mac, Linux).Automatic Memory Management: Java handles memory cleanup seamlessly through built-in garbage collection, preventing memory leaks.Object-Oriented Programming (OOP): It uses classes and objects to make code modular, reusable, and highly scalable.Robust Security: Features like strong memory allocation, type-checking, and runtime exception handling make it highly secure.
