How to become a Java developer?

Updated on November 16, 2014

Who is a Java developer?

A Java developer is someone who not only involves in program/codes; he/she takes active participation throughout the software development life cycle, i.e., it is the job of a developer to analyze a problem, create system efficient solutions and then viably integrate the entire planning to deliver sound functionality.

A Java developer's job is to create and test various computer programs by using a programming language, which is called 'Java'. Originally created by Sun Microsystems, Java language powers all types of programs-from online games to business applications. Although, it is a computer language, but Java is different from other computer languages in various ways. For instance, it is designed to facilitate the creation of software that can easily be run on various types of computers like Windows PCs and Macs.

The majority of Java developers are working in diversified industries, ranging from healthcare, automobile to content management. It is the job of a Java developer to create different dynamic applications and websites. Some developers design interfaces; while others take care of the work that's completely behind the picture.

Java developers are also responsible for programming different Java/Java scripts on different websites in order to help different processes within a company to perform umpteen computerized tasks, that may also help in complex processing. Java developers also work closely with JavaScript to create security settings that would help users and process different business transactions.

Java developers frequently interact with their team and end-users in order to ensure that the scripting language explicitly deals with varied requirements. On the basis of received feedback, they improve the functionality of a website and also the overall design of the website. Other Java job duties involve collecting and documenting user requirements, closely analyzing data and conducting quality assurance testing.

Types of Java developer jobs

Although, the basic skills required for Java development may remain same throughout the industry; there are many different options which exist with Java developer jobs. Typically, Java related careers fall into four types of categories- Java programmers, Java Web developers, Java web masters and Java software engineers. Each developer specializes in a particular area which eventually becomes their expertise.

A Java programmer job mainly involves software programming and developing. It can also includes testing and information gathering. Like other developer jobs, programmers usually work within a common area of expertise, like video-game programming. If we talk about the video-game programming, then the developer would work towards creating programmes and implement sounds, graphics & behaviors which are closely associated with the game.

After completing programs, it is the Java programmer job to test them in order to ensure that they are working properly. In many cases, they will also need to train others, like clients, on how to use programs.

It is the task of a Java web developer to create user-friendly websites. These web developers judiciously use their technical prowess and knowledge in designing and creating various web sites on the basis of client's individual requirements. In order to impart an impeccable web experience, web developers will create different applications and other related softwares that help the user to navigate through the website in an easy way. Some of the examples are- making interactive drop down menus, buttons, etc.

The next profile comes is of the Java web masters, whose core work activities involve fulfilling all job duties of the website administrators. Under this profile, they do periodic maintenance of the website in order to ensure that it works smoothly and they alse make all requisite amendments, keeping software up-to-date and responding to all woes & user problems. They also work towards verifying the HTML validity and help in improving the overall structure of the website. It is the job of a web master to keep their websites compatible with new browsers and operating systems.

The last category is of a Java software engineer. It is the task of a Java software engineer to create and implement various softwares on the basis of client's requirements. Once the software is developed, it is their responsibility to maintain it and ensures that it runs smoothly. Also, Java software engineer solves any compatible related issues that may arise after the updating of new software.

Did you know?

Originally, Java was called OAK and was mainly designed for set top boxes and hand-held devices. Java source code files (files with the .java extension) are stored in a format named, as bytecode (files with the .class extension), which can be executed by a Java interpreter. Usually, Java code can easily run on all computers because Java interpreters and runtime environments, which are most commonly called Java Virtual Machines (VMs), work on all operating systems, including Windows and LINUX. It is feasible to convert bytecode directly into machine language instructions with the help of the just-in-time compiler (JIT).

The Java language has various attributes that make it well-suited for different uses in the World Wide Web. Also, small Java applications are known as Java applets and can easily be downloaded from the Web server. It can be run on your computer system through various Java-compatible Web browsers, like Netscape Navigator or Microsoft Internet Explorer.

History of Java Language

James Gosling, Mike Sheridan, and Patrick Naughton started the Java language project in the year 1991. Earlier, Java was mainly designed for the interactive television, but at that time it was too advanced for the television industry. Originally, the language was called Oak, after an Oak tree which was standing outside the office of Gosling; then it got the name 'green', and finally renamed 'Java', after the Java coffee.

In the year 1995, Sun Microsystems released the first implementation as Java 1.0. It was launched with a promise of "Write Once, Run Anywhere" with no cost run jobs. Most of the leading web browsers used Java applets within web pages, and in a very short span of time, Java gained immense popularity.
