Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine).. In java programming language there are three types of loops; while, for and do-while. Java is one of the most popular programming languages used to create Web applications and platforms. It was designed for flexibility, allowing developers to write code that would run on any machine, regardless of architecture or platform. According to the Java home page, more than 1 billion computers and 3 billion mobile phones worldwide run JavaBased on a C and C++-based syntax, Java is object-oriented and class-based. Developers adopt and use Java because code can be run securely on nearly any other platform, regardless of the operating system or architecture of the device, as long as the device has a Java Runtime Environment (JRE) installed. The JRE varies depending on the specific type of device, but essentially it runs a "virtual" machine, or environment, that translates the code into an application or program.
