Step 1: Platform Independence. Java is platform-independent due to its "Write Once, Run Anywhere" philosophy. Java programs are compiled into bytecode, which can be executed on any platform that has a Java Virtual Machine (JVM).
Step 2: Object-Oriented. Java is an object-oriented programming language, meaning it promotes concepts like inheritance, encapsulation, and polymorphism, which help in building scalable and reusable code.
Step 3: Security. Java provides a secure environment by using bytecode verification and a security manager to restrict access to certain system resources.
Step 4: Rich API. Java provides a rich set of libraries (API), which simplifies many programming tasks such as file handling, networking, and database access.
Step 5: Multithreading Support. Java supports multithreading, allowing the development of highly responsive and efficient programs that can perform multiple tasks concurrently.
