Why is Java Important in todays IT industry?
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 Java.
Java is used to build applications and platforms for a number of devices, including computers, laptops, gaming consoles, Blu-ray players, car navigation systems, medical monitoring devices, parking meters, lottery terminals and smartphones. It is also a key language for networking, particularly for data centers that store and transfer Web-based data.
Java is also used to create miniature, dynamic programs that run alongside or are embedded within Web pages. These programs are called applets and can be used to display maps, weather, games or other interactive widgets or tools on a Web page.
Based 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.
