Courses Description

Java is a general-purpose computer programming language that is object-oriented, concurrent and class-based and designed to have minimal dependencies when it comes to its implementation. A programming world without Java is inconceivable. Widely used in the distributed environment of the internet, it is one of the most popular programming languages for Android smartphones and favoured for development of devices and software applications. The functioning of a large number of websites and applications depends on the installation of Java which is fast, secure and reliable. From data centres and laptops to gaming consoles, scientific supercomputers and the Internet.
