FAQs

What is the average salary of a java programmer?

According to Salary.com, the estimated total pay for a Java programmer is $102,526 per year in the U.S., with an average salary of $95,541 per year. The estimated additional pay is $6,984 per year, which can include cash bonuses, commissions, tips, and profit sharing.

What does a Java programmer do?

According to Indeed.com, a Java developer is a skilled programmer who utilizes their expertise to develop and test software using the Java programming language. They create, modify, monitor, and fix software across various platforms. Java developers work closely with web developers, designers, and software engineers to develop fully integrated programs and applications for their clients.

What is the difference between a programmer and a developer?

According to Indeed.com, though developers and programmers have similar job duties and abilities, they are two different professions. A programmer is a technician who specializes in coding, whereas a developer is a designer or project manager who can also code.

A programmer's primary focus is writing code and implementing specific functionalities based on given specifications. They possess strong coding skills and expertise in specific programming languages. In contrast, a developer's scope of work is broader and encompasses multiple stages of the software development lifecycle. They have a comprehensive skill set, including knowledge of software architecture, design patterns, and other related technologies. Developers adopt a more holistic approach to problem-solving and are responsible for coordinating various aspects of the development process.
