Role of a Java Developer

A Java Developer is responsible for the programming and development of applications and software using the popular programming language, Java.

Before we dive into the specifics of a Java developer role, let’s start with the basics. Java is a programming language, widely considered to be one of the most popular in the world. A report 9 million developers use Java regularly. Not to be confused with JavaScript, Java itself is also a platform for application development, which many programming languages are not.

In the world of computer programming, Java is one of the older languages. Sun Microsystems developed the language in 1995 based on the syntax of C and C++. Today, Java is part of Oracle.

Java is a concurrent, class-based, and object-oriented programming language. It was initially designed to have as few implementation dependencies as possible, which lead 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.

Because of its inherent linguistic design, Java has many benefits that behoove companies. Java-based applications are known for their speed and scalability. Its efficient processing speeds are used in software, computer games, and mobile Apps. (Indeed, Java is the programming language of choice for Android.)

Java is also a statically typed language, so that it brings a much greater degree of safety and stability to its programs compared to other popular languages. This safety and stability is a necessity for companies who require major bandwidth in their software and apps.

New programmers often start learning Java early because it’s easy to break into, though it does take time to master. Due to its ease of use, there are many Java developers for companies to hire.

Java is also an influential language, as many languages descended from it, including the popular PHP, Python, Scala, and JavaScript. Interestingly, PHP, a Java descendant, is used in over 82% of websites whose server-side programming is known.

Roles and Responsibilities of a Java Developer

The roles and responsibilities of a Java developer or Java engineer will vary greatly depending on the company and specific position. Here are common examples that many companies seek:

  • Designing, implementing, and maintaining Java applications that are often high-volume and low-latency, required for mission-critical systems
  • Delivering high availability and performance
  • Contributing in all phases of the development lifecycle
  • Writing well-designed, efficient, and testable code
  • Conducting software analysis, programming, testing, and debugging
  • Managing Java and Java EE application development
  • Ensuring designs comply with specifications
  • Preparing and producing releases of software components
  • Transforming requirements into stipulations
  • Support continuous improvement

Qualifications

A professional certification is recommended when looking for jobs in in Java Development. Most employers will require applicants to have a degree in computer science, information systems, mathematics or any other closely related field. Computer science degrees tend to be more preferable as these courses tend to offer tasks related to Java programming with coursework including data structures, computer architecture, database management, statistics and technical writing.

However, applicants without any kind of degree or education can still be considered if they can show significant knowledge and experience of programming in Java.

Future of Java Programming

According to our survey results, more organizations are turning to Java as the language of choice to help modernize their applications. Not surprisingly, demand for Java Developers is expected to grow between now and 2024 by up to 19%.
