Java Programming

Java Programming is the practice of developing software using Java, a high-level, class-based, object-oriented language renowned for its "write once, run anywhere" (WORA) philosophy. This is achieved by compiling Java code into bytecode that runs on a Java Virtual Machine (JVM), allowing applications to be platform-independent. Due to its robustness, security features, and extensive libraries, Java is a dominant force in enterprise-level back-end development, Android mobile app creation, and large-scale data processing, making it a foundational language in both academic and professional software engineering.
