What is Java?

Java is a high-level, object-oriented programming language that was developed by Sun Microsystems in 1995 and is now owned by Oracle Corporation. Renowned for its portability, Java follows the "write once, run anywhere" philosophy, meaning that code written in Java can run on any device or operating system that supports the Java Virtual Machine (JVM). This cross-platform capability has made Java a popular choice for developing a wide range of applications, from mobile apps and enterprise software to web-based services and large-scale distributed systems.

Java is designed to be easy to learn and use, with a syntax that is clear and relatively simple compared to other languages like C++. It supports automatic memory management through garbage collection, which helps developers avoid common programming errors such as memory leaks. Additionally, Java’s robust standard library provides a wide array of pre-built functionalities, which significantly speeds up the development process. Java’s versatility, combined with its strong community support and extensive libraries, has made it one of the most widely used programming languages in the world, powering millions of applications and systems across various industries.
