- Create Enterprise Software
Java is considered an easy-to-use and platform-independent programming language. It is used to create a distributed environment and facilitates distributed computing. Several components of the Java programming language make it easy to write human-readable source code. Java components include Java Development Kit (JDK), Java Virtual Machine (JVM), and Java Runtime Environment (JRE).
Java programming language can be an ideal choice for developers who can help develop any application or software. It comes with several benefits such as:
- A large community that offers tons of resources to learn from.
- It is an open-source programming language with a rich API and a comprehensive set of tools.
