What is Java? How does it works?

Java is a high-level, object-oriented programming language that was originally developed by Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. It is designed to be portable, meaning that it can be used on any platform, including desktop computers, mobile devices, and servers. Java is also known for its security features, which make it a popular choice for building applications that require a high level of security.
Java code is written in a text editor or integrated development environment (IDE) and then compiled into bytecode, which is a low-level, platform-independent code that can be executed on any machine with a Java Virtual Machine (JVM). The JVM is a virtual machine that interprets the bytecode and executes it on the host machine.
Java also comes with a large standard library that provides a range of functionality for common programming tasks, such as reading and writing files, networking, and working with databases. Additionally, there are many third-party libraries and frameworks available for Java that can be used to extend its functionality and simplify common programming tasks.
Java is used in a wide range of applications, from desktop applications and games to web applications and enterprise systems. Its popularity is due to its platform independence, robustness, and security features, as well as the large community of developers who contribute to its development and support.
