What is Java?

Introduction​

Java is a powerful and popular programming language used to create mobile applications, desktop applications, web applications, and many enterprise-level software.

The code written in Java is platform-independent. We can write code in Java and run it anywhere with Java Virtual Machine(JVM). Java uses OOP(Object Oriented Principles) so we can create modular and reusable code.

Java is rich in libraries and a secure and robust programming language. Java has strong memory management and error-handling techniques. Java is good for both experts and beginners.

Note: If you already know programming languages like C and C++, learning Java can be comparatively easy for you.
