What Does a Java® Developer Do?

By T. M. Robertson
Updated: May 17, 2024

A Java® developer is tasked with the job of creating interactive Web-based applications that include changing images, sounds, and animations, among other things. With these applications, the developer creates an interactive environment for users to experience while they are maneuvering around a given Web site. Most employers of Java® developers desire job applicants to have either a four-year degree in a computer-related field, or a degree with a business-related major accompanied by a post-graduate certificate in a computer-related field. Occasionally, years of specialized experience will be accepted in lieu of the required years of education. The most desired job-related skills include the ability to pay great attention to detail, the ability to multitask, good communication skills, and strong analytical skills.

Typical work for a Java® developer involves creating and implementing interactive Web-based applications for clients. These applications are based on JavaScript, a unique programming language that allows for interactivity between Web-based browsers and applications. Through JavaScript, a Java® developer will create an interactive environment for the user based on the client's specifications. Applications can include items such as changing images, utilization of sounds associated with certain actions, and drop-down menus that are animated or changing. In addition to just creating applications, developers may also work on training others in how to use them and also on testing applications to make sure they are operating in the manner intended.

In order to become a Java® developer, one must first acquire the proper education. While some manage to find work with only a two-year degree, a four-year degree is preferred. Desired majors are generally in the areas of mathematics, computer sciences, and information systems, but some employers also seek out candidates from other majors that have a good understanding of the business side of things. These candidates usually obtain post-graduate certificates in one of various different computer-related subjects. Occasionally, a candidate without a college degree can find work as a Java® developer, but this is uncommon and usually only happens when a candidate has years of related experience and expertise in the field.

Qualified Java® developers must have strong analytical skills and also pay great attention to detail because the process of creating the desired interactive programming can be quite complex. Multitasking is another useful skill, as developers often juggle their time between the tasks of creating, designing, managing, and analyzing several different projects all at once. Developers must also have good communication skills, as they must be able to communicate with their clients in order to create the applications that clients envision. The ultimate goal of the Java® developer is to create and maintain user-friendly Web sites that meet their clients' specifications.
