  • Ability to gather accurate requirements and work closely with stakeholders to prioritize tasks and the scope of development.
  • Strong attention to detail with the ability to identify errors and make adjustments in a testing environment.

Salary Outlook

The use of Java seems to be more in quality than in quantity, as only 2.6 percent of all websites utilize Java. But, some of the biggest, most highly trafficked websites depend on Java, such as LinkedIn, Chase, and even the IRS. While Java can be used in many industries, it is e-commerce and web-dependent companies that rely on quality Java developers. As a company grows, they tend to switch over to Java for better speed and stability. Java is also said to be the future of Big Data, which could give Java developers an even stronger salary outlook.

According to Payscale, Java developers make an average base salary of $73,268 in the United States.
