Java is fast emerging as one of the major computer languages. It consists of both C and C++ computer languages. This combination means that computer machinery reads these two codes as a one purpose programming language. The language directs the computer to perform certain actions, from opening files to navigating websites. The goal of any computer language is to control a computer's operations, enabling users to command it at will without computer crashes or system freezes.
Besides language, Java can also be considered as a platform. However, it is a software platform rather than a hardware platform like Windows or Linux system. In other words, Java functions on top of the hardware platform as a Java Virtual Machine (JVM). JVM processes the user's commands and compiles the command's language into instructive byte codes that triggers the computer to perform an action. It could be said that Java translates between the user and operating system.
Java is so popular because it delivers high performance with small security risks. First, it is simple to use and operates securely both inside and outside the JVM. Secondly, it is dynamic and efficient thanks to its byte codes, which compresses many codes of information. Java is often described as ''robust'' because it can be used among differing platforms and causes less ''computer-crashing'' than other languages. Java offers a virtual, all-encompassing ''toolset'' that permits users to fully engage with their computers, rather than toil over an unresponsive machine.
There are specific ways in which Java is user friendly. Firstly, programmers often ''enable'' Java applets onto Internet browsers that help users navigate websites. Written in Java language, applets interact with the JVM to generate attractive graphics that make a website more navigable. Java applets are not limited to a specific computer platform, and can be used on Windows, UNIX, and Linux systems. However, applets cannot be implemented by HTML language. This is partially why people hire Java developers to program Java onto their websites. Applets also enable interactive computer games, with Java acting as the interface between the user and the operating system. Moreover, Java enables Internet chat rooms and animated graphics.
Another widespread Java application is the Java servlet. The servlet is not visible to the user since it is a ''server-side'' application, unlike the applet, which is a ''client-side'' application. A servlet basically, directs the server to perform the user's instructions. A servlet works with Internet HTTP requests. Once a HTTP address is entered, the servlet commands the server to bring up that website address. Java developers often use servlets to add eye-catching content to a website.
The majority of computer programmers learn how to program Java because it is in steady demand. Since its launch in 1995, it has changed the face of Internet browsing by providing such legible client-server interfaces. Fortunately, for programmers, Java is a relatively simple language to learn since most programmers are already familiar with C and C++ languages. Moreover, programmers write less code in Java and it has been honed to eliminate language errors used by C and C++. Therefore, it allows for fewer debugging and ''garbage-collection'' processes.
Developers who want to add Java to their repertoire can choose from numerous learning options. Java courses are available at many colleges and universities, where software developers can learn very rapidly with mentors. Java courses are also available online, such as Java Tutorial offered by the Java homepage, at Sun Microsystems website. In addition, Sun Microsystems offers a range of courses in Java, and maintains a helpdesk where users can get additional feedback. These courses are offered in both web-based and instructor-led formats. Java learners can choose the teaching method that best suits them. Java programmers can also become Java-certified by Sun Microsystems after completing a specified course curriculum. Those who are certified often encounter more job opportunities, some of them being 100k and above jobs.
Programmers specializing in Java programming are known as Java developers. Java developers must demonstrate familiarity with all available editions of Java. Java developers can advance to senior Java developers. Senior Java developers usually have about a decade of Java-programming experience, working with virtually all prevailing computer platforms. However, even if developers specialize in Java, they always have wide knowledge of other programming languages, such as HTML, XML, and C# languages.
Most Java developers work for Information Technology (IT) staffing firms, where they are contracted by other firms to program Java onto company computers. They can also work in-house at large corporations, such as software and telecommunications corporations.
Java developers earn about $50,000 in their first year. Their salary rapidly increases as they accrue more years, with most developers making about $59,000 per year after four years of professional experience. Developers who want to find 100k jobs will likely discover them at a job site for 100k salaries.
