Java developers create complex web-based applications. Some examples include animated drop-down menus, images that change as a mouse moves over them, and sounds that play when clicked. Java is used extensively on e-commerce sites to collect data and validate user information. It is the job of Java developers to use this scripting language to modify the design and functionality of websites as requested by their clients. Java developers may write programs themselves or revise existing applications. They also identify opportunities to fine-tune and optimize applications of java developed projects. Java developers will often test programs to verify that they work correctly. This responsibility includes resolving technical issues through debugging, research and investigation. Java developers will also often mentor and provide technical guidance and instruction to lower level IT staff, assisting with specific problems requiring a broad knowledge of subject matter processing.
Technology in the IT world is constantly changing so knowledge becomes outdated in a few years. Therefore, a love of learning is essential for Java developers. Good researching skills are also important because there will always be new technologies to learn about. Java developers typically work on a team, so being a team player is extremely important. Good communication skills are also a must because Java developers must be able to communicate effectively with their team and with clients.
