The Java developer will report to a senior project manager or an overall IT manager.

Java is a concurrent, class-based, and object-oriented programming language. It was initially designed to have as few implementation dependencies as possible, which led to the term “write once, run anywhere” (WORA). This means that compiled Java code can run on all platforms with no need for recompiling the code. A Java Developer is responsible for planning, designing, developing, and managing Java-based applications and software.
