JAVA SPECIALTY

Java is an object-oriented computer programming language created by James Gosling and Patrick Naughton employees of Sun Microsystems with the support of Bill Joy (co-founder of Sun Microsystems in 1982), officially presented on May 23, 1995 at SunWorld.

The main feature of the Java language is that software written with it is very easily portable to multiple operating systems such as UNIX, Windows, Mac OS or GNU / Linux with little or no modification. This is the platform that guarantees the portability of applications developed in Java.

The language largely resumes the syntax of the C ++ language, widely used by computer scientists. Nonetheless, Java has been stripped of the finer and more confusing concepts of C ++, such as pointers and references, and multiple inheritance replaced by the implementation of interfaces. The designers favored the object-oriented approach so that in Java everything is object except primitive types (integers, floating point numbers, etc.)

Java allows you to develop client-server applications. On the client side, applets are at the origin of the notoriety of the language. It is especially on the server side that Java has imposed itself in the business world thanks to servlets, the server side of applets, and more recently JSP (JavaServer Pages) which can replace PHP, ASP and ASP.NET .
