Java Introduction
What is Java?
Java is a high-level, class-based, object-oriented programming language designed to have as few implementation dependencies as possible. Java is widely known for its platform independence, which means that compiled Java code can run on all platforms that support the Java Virtual Machine (JVM). It follows the principle of “write once, run anywhere,” making it highly portable. Java is also known for its simplicity, security, robustness, and ability to handle large-scale applications efficiently. It is extensively used in developing web applications, mobile applications, enterprise software, and cloud-based systems.
Java is a popular and powerful programming language, created in 1995.
It is owned by Oracle, and more than 3 billion devices run Java.
It is used for:
- Mobile applications (specially Android apps)
- Desktop applications
- Web applications
- Web servers and application servers
- Games
- Database connection
- And much, much more!
