Until now, Java is one of the most popular programming languages. It is used for designing and developing websites, web applications, mobile applications, etc. It is also used in wide range of fields, such as finance, publishing, non-profit and healthcare institutions. You should learn some knowledge about Java technology.

According to Wikipedia, Java is a set of several computer software and specifications developed by Sun Microsystems, later acquired by Oracle Corporation, which provides a system for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers.

Java includes several technologies in its fold like Java ME or J2ME, J2EE, JSP, Servlet, VoXML, Linux, UNIX, open source solutions, etc. They are used in combination as well as standalone for developing any application. These technologies have their own utility and benefits.

Java technologies to use in web applications

You can find web applications on the Internet. Many of these web applications are used to process online forms, take orders within online stores, tally voting polls, allow users to book a flight for their next business trip, or simply to display the user's login name.

A web application often consists of nothing more than one page created with the JavaServer Pages (JSP) technology. Sometimes you will combine three or more such technologies. No matter how many you end up using, it's good to know what is available to you and how you can use each one in a web application.

At the same time, Java technology is not only a programming language but also a platform.

A platform is the hardware or software environment in which a program runs. We mention about some of the most popular platforms like Microsoft Windows, Linux, Solaris OS, and Mac OS. Most platforms can be described as a combination of the operating system and underlying hardware. The Java platform differs from most other platforms in that it's a software-only platform that runs on top of other hardware-based platforms.

Why software developers choose Java?

Java has been tested, refined, extended, and proven by a dedicated community of Java developers, architects and enthusiasts. Java is designed to enable development of portable, high-performance applications for the widest range of computing platforms. By making applications available across heterogeneous environments, businesses can provide more good services and boost end-user productivity, communication, and collaboration. At the same time, it greatly reduce the cost of ownership of both enterprise and consumer applications.

With Java, developers can do the following things:

  1. Write software on one platform and run it on virtually other platforms.
  2. Develop server-side applications for online forums, stores, polls, HTML forms processing, and more.
  3. Combine applications or services using the Java language to create highly customized applications or services.
