A Java developer will be in charge of the design, develop, and managing of Java-based applications. Because Java is so widespread, especially in large organizations, daily roles vary widely, but may involve a specific application, or working on multiple applications simultaneously.

These professional programmers are responsible for developing applications and software using the Java programming language, working with other software engineers, web developers, and others using Java to develop business applications, websites, and more.

They are active throughout the product or solution development cycle. They are able to identify and analyze any problems that arise and recommend effective solutions. Employers seek Java developers as needed, and they are usually in high demand.

Before We Dive into the Details, Let’s Start with the Basics

Java is a programming language widely considered to be one of the most popular languages in the world. Nine million developers use Java regularly.

Not to be confused with JavaScript, Java is itself a platform for developing applications and many programming languages are not.

Java is a class-based, object-oriented, concurrent programming language. It was originally designed to have as few implementation dependencies as possible, which gave rise to the term «write once, run anywhere» (WORA). This means that the compiled Java code can run on all platforms without having to compile the code. Because of its language design, Java brings many benefits to businesses:

Java applications are known for their speed and scalability. Java’s efficient processing speed is used in software, computer games, and mobile applications. (In fact, Java is Android’s programming language of choice.); Java is a statically typed language, so it provides programs with a higher degree of security and stability than other popular languages. This security and stability is a must for businesses whose software and applications require more bandwidth. There is no shortage of talent, although new programmers generally start learning Java early because it is easy to understand. Due to its ease of use, companies can hire many Java developers.

Java Developer Job Roles

The role of a Java developer can vary greatly depending on the company and the position. These are some of the most common roles and tasks:

  • Participate in the software development process.
  • Develop, deploy, and maintain high-volume, low-latency Java applications
  • Analyze user needs to define business goals.
  • Visualization of characteristics and functions of the system.
  • Define the objectives and functions of the application. Ensure application design meets business goals.
  • Develop and test software.
  • Recognize and resolve technical problems.
  • Create detailed design documents.
  • Propose changes to the current Java infrastructure.
  • Develop technical projects for the development of applications.
  • Develop multimedia applications.
  • Write well-designed and testable code.
  • Analyze software, programming, testing, and perform regular clean ups.
  • Run and understand Java and Java EE application development.
  • Develop documentation to help users.
  • Preparation and Versioning of Software Components.
  • Support continuous improvement; explore alternatives and methods, and submit for architecture review Ability to write clean and readable Java code.
  • Experience in managing external and embedded databases.
  • Understand the basic design principles behind a scalable application.


Some of the Key Java Developer Skills

Java developers need a wide range of skills, from a deep understanding to a firm knowledge of current developments. Java experts also need to know how the development process works and how to switch between environments where code is executed. Here are some necessary skills for a Java developer :

  • Skills and a good understanding of Java and its environments.
  • Solid knowledge of object-oriented programming (OOP) patterns and concepts.
  • Familiarity with different architectural designs and patterns.
  • Ability to write reusable Java libraries.
  • Java concurrency pattern know-how.
  • Basic understanding of MVC (Model-View-Controller) pattern concepts, JDBC (Java Database Connectivity) and RESTful web services.
  • Experience working with popular web application frameworks like Play and Spark.
  • Relevant knowledge of Java GUI frameworks like Swing, SWT, AWT as per project requirements.
  • Ability to create database schemas that characterize and support business processes.
  • Developed skills in JVM (Java Virtual Machine).
  • Set up automated test platforms and unit tests.
  • In-depth knowledge of code version control tools, for example Git.
  • Understanding of build tools like Ant, Maven, Gradle, etc.
  • Continuous integration experience.

Other required Java developer skills include basic knowledge of:

  • JavaServer pages (JSP) and servlets.
  • Web frameworks like Struts and Spring.
  • Service Oriented Architecture.
  • Know and understand HTML, JavaScript, CSS, JQuery.
  • Markup languages like XML, JSON.
  • Abstract classes and interfaces.
  • Constructors, lists, maps, sets.
  • IO file and serialization.
  • Multithreading and Synchronization.


The Java Developer Team

As a Java developer , you can be a part of your organization’s IT team. Depending on your company structure, a single project may involve a single IT team or several smaller IT teams.

A developer may report to a senior program manager or general IT manager, who in turn reports to the CIO or senior IT management. When searching for talent, employers often hire Java developers based on their experience.

Job positions usually are for:

  • Entry level Java developer
  • mid-level developer
  • Senior Java Developer

Each of these ranks has different responsibilities. An Entry Java developer may be assigned the architecture of the application, while a Senior Developer may be responsible for the overall operation of the project, including ensuring a smooth architecture and leading the team.

A typical team for a Java developer job might include some of the following positions:

  • Project manager
  • Chief designer
  • Programmer

Upon request, some of these features may overlap or be combined into one. If Java developers are veterans, they may be responsible for team oversight and liaison with project stakeholders and beta testers.

Although not typically part of the core development team, project stakeholders and beta testers have a great deal of influence on the project, so having senior Java developers as mediators is critical to its overall success.

Java Programming as a Profession

A Java Developer has many good opportunities in the IT industry, from established roles to highly developed and transformational roles. Still not sure if you have the skills to land a Java developer job? There are several ways to get the skills you need to land the job you’ve always wanted.

You can, for example, get a job as a junior developer. If your knowledge of Java isn’t as good as it should be, this is a good place to start. When you walk in the door as a junior developer, you can build your IT career by gaining relevant experience in the IT industry. You can also build a solid foundation in Java, the most widely used programming language in software development, by taking an online Java certification course. By learning more about middleware technologies and other programming languages, you can also take your career in other exciting directions.

The Future of Java Programming

Based on survey results, more and more organizations are using Java as their language of choice to help modernize their applications. Not surprisingly, demand for Java developers will grow 19% by 2024. In addition to hiring Java developers who can support application modernization across industries, organizations need to understand that Java is different from other mainframe applications.

It runs on Java virtual machines (JVMs), which manage their own resources and can be deployed anywhere. If the JVM uses too many resources, it affects the performance and availability of other workloads.

Java’s history has been a mainstay of programming languages for over 20 years, causing the industry to question its longevity. Java has been the world’s most popular language for over a decade. If you are interested in programming and are new to this world, this is a great starting point. Diversifying your programming language skills can lead to more lucrative roles because you can program in multiple languages.
