Java

Java is a high-level, class-based, object-oriented programming language designed to have as few implementation dependencies as possible. It is a general-purpose language intended to let application developers write once, run anywhere (WORA), meaning that compiled java code can run on all platforms that support java without the need for recompilation. Key features include platform independence through the java Virtual Machine (JVM), object-oriented principles like encapsulation and inheritance, and robust libraries for various functionalities.

Java meaning with examples

• Software engineers often use java to develop enterprise applications. The language's portability allows them to deploy the application on diverse operating systems. Complex systems like banking applications frequently leverage Java's robustness and multi-threading capabilities, ensuring smooth transactions and data management. Developers also use java to create Android mobile applications using frameworks like Android Studio and the Android SDK.
