What does a java/j2ee developer do?
Java developers are in charge of the design, development, and management of Java-based applications. Whereas, J2EE or Java 2 Platform Enterprise Edition developers are responsible for developing web and software enterprise-internet level applications. Both developers utilize the Java programming language, but the first one develops desktop-based applications while the later develop enterprise-related applications. Java developers have many roles and responsibilities, and they vary based on the applications that they develop and design.

Java/j2ee developers often use customer-service skills in their day-to-day job, as shown by this real resume: "developed enterprise solutions for customers to order contact lenses online involving j2ee, struts, and hibernate technologies. "
Creativity. Another essential skill to perform java/j2ee developer duties is creativity. Java/j2ee developers responsibilities require that "web developers often are involved in designing the appearance of a website and must make sure that it is appealing as well as functional." Java/j2ee developers also use creativity in their role according to a real resume snippet: "project description: logical inventory management system (lims) provides a ui for the customer support provisioning and troubleshooting services. "
Detail oriented. java/j2ee developers are also known for detail oriented, which are critical to their duties. You can see how this skill relates to java/j2ee developer responsibilities, because "web developers need to have an eye for detail, because a minor error in coding could cause an entire webpage to stop working." A java/j2ee developer resume example shows how detail oriented is used in the workplace: "used xml parser converts an xml document into an xml dom object * used object oriented design patterns to build components. "

Compare different java/j2ee developers
Java/j2ee developer vs. Mobile applications developer
A mobile application developer is responsible for designing programming applications for mobile devices according to clients' specifications and business demands. Mobile application developers must have excellent knowledge of the technology industry, as well as computer system commands to develop efficient scripts and smooth navigation of operating systems. They analyze the clients' needs and recommend application solutions within their budget limitations and timeframe. A mobile application developer identifies inconsistencies and glitches with the output before submission to ensure its stability and optimal performance.
While similarities exist, there are also some differences between java/j2ee developers and mobile applications developer. For instance, java/j2ee developer responsibilities require skills such as "database," "log4j," "design patterns," and "jdbc." Whereas a mobile applications developer is skilled in "c++," "c #," "mobile development," and "react native." This is part of what separates the two careers.
Mobile applications developers really shine in the pharmaceutical industry with an average salary of $107,574. Comparatively, java/j2ee developers tend to make the most money in the finance industry with an average salary of $100,301.mobile applications developers tend to reach higher levels of education than java/j2ee developers. In fact, mobile applications developers are 5.3% more likely to graduate with a Master's Degree and 0.5% more likely to have a Doctoral Degree.Java/j2ee developer vs. Java programmer
Java programmers design and develop programs with the goal of not taking up too much data and less to almost no latency that can be useful to their users every day. They aim to write testable, well designed, and efficient computer codes. Java developers need a range of skills, from a thorough knowledge of the basics to an understanding of the latest developments. Programmers also need knowledge beyond the java language itself. Their skills should include knowing how the development process works and how the apps function in which the code runs.
Each career also uses different skills, according to real java/j2ee developer resumes. While java/j2ee developer responsibilities can utilize skills like "javascript," "database," "junit," and "test cases," java programmers use skills like "database connectivity," "application development," "unit test cases," and "windows xp."
Java programmers earn a lower average salary than java/j2ee developers. But java programmers earn the highest pay in the finance industry, with an average salary of $94,924. Additionally, java/j2ee developers earn the highest salaries in the finance with average pay of $100,301 annually.java programmers earn similar levels of education than java/j2ee developers in general. They're 4.7% more likely to graduate with a Master's Degree and 0.5% more likely to earn a Doctoral Degree.What technology do you think will become more important and prevalent for java/j2ee developers in the next 3-5 years?

Java/j2ee developer vs. Web application developer
A web application developer is responsible for designing website and system applications following clients' specifications and business' needs. Web application developers utilize their expertise in programming languages and system codes, ensuring the efficiency and smooth navigation of the website. They also run multiple diagnostic tests on the output before release, identifying inconsistencies, and addressing incompatibilities on browsers and devices. A web application developer should be detail-oriented and highly-technical as this job requires excellent digital knowledge to manage complex systems.
Some important key differences between the two careers include a few of the skills necessary to fulfill the responsibilities of each. Some examples from java/j2ee developer resumes include skills like "mvc," "maven," "log4j," and "design patterns," whereas a web application developer is more likely to list skills in "python," "application development," "web forms," and "php. "
Web application developers make a very good living in the finance industry with an average annual salary of $88,928. On the other hand, java/j2ee developers are paid the highest salary in the finance industry, with average annual pay of $100,301.Most web application developers achieve a similar degree level compared to java/j2ee developers. For example, they're 2.7% less likely to graduate with a Master's Degree, and 0.5% less likely to earn a Doctoral Degree.Java/j2ee developer vs. Front end developer
Front-end developers architect and develop applications and websites through web technologies. They are responsible for the implementation of visual elements that every user sees and interacts with on web applications. They are often supported by the back-end web developers who are in charge of server application logic and integration. They must know CSS or HTML.
