Java

Java is a high-level, object-oriented programming language designed for portability and reliability, running on the Java Virtual Machine (JVM) to enable 'write once, run anywhere' functionality. It is widely used for building enterprise-scale applications, Android apps, and large-scale systems due to its strong typing, memory management, and extensive standard library.

Also known as: Java SE, Java EE, J2EE, Core Java, Java Programming Language
