Java - Tutorial

Java is a high level, robust, object-oriented, class-based, concurrent, secured and general-purpose programming language. The syntax Java is very much similar to C and C++. It is used to create window-based applications, mobile applications, web applications and enterprise applications. Applications developed in Java are also called WORA (Write Once Run Anywhere). This implies that a complied Java application is expected to run on any other Java-enabled system without any adjustment. As of now, Java is one of the most popular programming languages in use particularly for client-server web applications.
