Java is a high-level, object-oriented programming language that was developed by Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. It is one of the most popular programming languages in the world and is used to create a wide range of applications, from mobile apps and games to enterprise software and web applications.
Java is known for its "write once, run anywhere" (WORA) philosophy, which means that Java programs can be run on any platform that has a Java Virtual Machine (JVM) installed, regardless of the underlying operating system. This makes it a popular choice for developing cross-platform applications.
Java is also known for its robustness, reliability, and security features. It has a large and active community of developers who contribute to its development and provide support for other developers.
Java has a wide range of libraries and frameworks, such as Spring, Hibernate, and Struts, which make it easier to develop complex applications. It is also used extensively in big data processing, machine learning, and cloud computing.
