Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is widely used for building enterprise-scale applications, mobile applications, and web applications. Java's design principles promote portability, making it a popular choice for developers.
- Platform Independence: Write once, run anywhere (WORA) capability through Java Virtual Machine (JVM).
- Object-Oriented: Encourages modular programming through the use of classes and objects.
- Rich API: Extensive libraries and APIs for various functionalities.
- Automatic Memory Management: Built-in garbage collection helps manage memory effectively.
- Multithreading: Supports concurrent programming with built-in multithreading capabilities.
