Java is a widely used object-oriented programming language and software platform that runs on billions of devices, including notebook computers, mobile devices, gaming consoles, medical devices and many others. The rules and syntax of Java are based on the C and C++ languages.
One major advantage of developing software with Java is its portability. Once you wrote code for a Java program on a notebook computer, it can be easily moved to a mobile device
If you are an enterprise application developer, you know what Java is and it’s likely that your organization already has thousands, even millions, of production line code written in Java. You likely need some level of Java expertise to allow you to troubleshoot, maintain and upgrade your existing codebase.
However, it would be a mistake to view Java only in terms of legacy applications. The Java language forms the heart of the Android operating system, which powers by far the largest share of the world’s smartphones. Java is also among the most popular languages for machine learning and data science applications. Its robustness, ease of use, cross-platform capabilities and security make Java the language of choice for internet solutions in many enterprise shops.
