Java is a class-based, object-oriented programming language which runs on the Java runtime environment, or JRE. One of the advantages of Java is its multi-threaded environment, which means that multiple tasks can be run at the same time.
Aside from being very well-documented, Java also boasts a large pool of third-party libraries which enables Java to fulﬁl a variety of desired functions. Once code has been developed on Java, it is possible to deploy it across different platforms.
How it’s used
Java is a ‘write-once, run-anywhere’ language. The Java platform differs from some other platforms in the sense that it is a software-based platform that runs on top of other hardware-based platforms.
Java is well known for its security. With Java, we can develop virus-free systems, as Java programs run inside a virtual machine sandbox.
Java presents several key beneﬁts for development. It’s modular, which means that it is easy to reuse code. It’s also regarded as being incredibly easy to pick up and learn, which means that the resulting source code of the application will be understandable to most developers. Its cross-platform capabilities make it the language of choice for many web applications.
