What is Java? Java is a high-level, object-oriented, and platform-independent programming language developed by Sun Microsystems (now owned by Oracle). It was released in 1995 and follows the principle of "Write Once, Run Anywhere" (WORA), meaning Java programs can run on any platform with a Java Virtual Machine (JVM). Key Features of Java: Platform Independence – Java code is compiled into bytecode, which runs on any operating system with a JVM. Object-Oriented – Java follows the principles of OOP (Object-Oriented Programming), improving code modularity and reusability. Secure – Java has built-in security features like the Security Manager, encryption APIs, and automatic memory management. Robust and Reliable – Java handles memory management (Garbage Collection) and exception handling efficiently. Multithreading – Java allows the execution of multiple threads simultaneously, improving performance. Scalability – Java is widely used in enterprise-level applications, making it ideal for large-scale systems. Applications of Java: 🔹 Web Development – Using frameworks like Spring Boot, Struts, and JSF. 🔹 Mobile Development – Java is the primary language for Android app development. 🔹 Enterprise Applications – Java EE (Jakarta EE) is used for large-scale business applications.
