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.
These skill sets are where the common ground ends though. The responsibilities of a web application developer are more likely to require skills like "python," "application development," "web forms," and "php." On the other hand, a job as a java/j2ee developer requires skills like "mvc," "maven," "log4j," and "design patterns." As you can see, what employees do in each career varies considerably.
Java/j2ee developers tend to make the most money working in the finance industry, where they earn an average salary of $100,301.
