Java programmers, also referred to as application software developers, apply Java software to bring ideas to life by coding the algorithms that direct the computer or device. Java engineers enable the seamless integration of modern technology into our daily lives as Java powers billions of devices. Java enables people to watch the latest Blu-ray technology, play video games, and is used in billions of mobile phones and appliances. 
Java programmers shape the way we use the Internet and technology through programs that make sophisticated web applications and software for data centers, animated sequences etc. Java software and applications gained huge popularity due to their cross-platform nature, as Java performs whether run by a Macintosh, Windows PC or UNIX system.  

Job Specification, Salary, Outlook
A Java engineer is responsible for the development and programming of software and applications using Java, one of the most popular programming languages. A Java programmer is a specialized type of developer who collaborates with software engineers and web developers to integrate Java into websites, software and applications. Java engineers analyze and identify problems and issues, create an effective solution, and are involved throughout the life cycle of a product’s development. Other duties include documenting and collating user requirements, quality assurance testing and data analysis. 
So how much do Java engineers earn? It depends on a number of factors, but the average salary for Java engineers in the United States is $72,020 per annum, with a range of $48,506 - $112,247. Factors that affect the level of salary include job location, technical skills, on-the-job experience, and academic background. In the UK, an average salary of £34,042 per year can be expected, with a range of £23,441 - £54,863. 

Job Description
Java engineers create sophisticated web-based applications, including sounds that can play when clicked, images that automatically change as a mouse moves over them, and animated drop-down menus.
