Growing your skills will help you succeed in your computer science career long-term, as you will be able to take on larger and more sophisticated projects. Many Java programs use SQL (Structured Query Language) when building and using databases. Ideally, you should also familiarize yourself with Oracle 12c, Microsoft SQL, and MySQL database systems.
Java is a programming language developers use for mobile, software, and web development. A small team called ‘The Green Team’ initially conceptualized Java in the early 1990s. That team included James Gosling, who later became known as the ‘Father of Java’ for his work. Gosling developed Java while working as an engineer at Sun Microsystems (a subsidiary of Oracle today).
Key Responsibilities of a Java Developer
If you work in a large business or busy industry, you may need to manage multiple updates simultaneously. If you are an experienced developer, you will need to understand your business’s programs, IT infrastructure, and program architecture in-depth. Understanding program architecture is crucial, as it’ll inform how you develop new projects. As many larger companies hire specifically to manage testing, cybersecurity, and vendor management, some Java developers have specialized roles.
Coursera’s editorial team is comprised of highly experienced professional editors, writers, and fact… As a Java engineer, your code should be easy to read and comprehend but straightforward to maintain. Additionally, if your code is well-documented, it becomes a collaborative asset, fostering effective teamwork and knowledge sharing. Uncover your website’s performance bottlenecks to deliver a better user experience. Joining the community is a great way to improve your problem-solving skills and technical knowledge. Developers primarily use Java for server-side development and JavaScript for client-side projects.
Java Developer with Spring Boot & REST
If you’re interested in becoming a Java developer, you can take six simple steps to build your skills and become a Java expert. As Java is an OOP language, you should understand the four OOP principles and the SOLID principles of OOP development. As you will need to design and build projects from the ground up, you must know how to construct a project’s architecture to be logical, consistent, and extendable long-term.
As a Java developer, you will need to deploy code to deliver it to users successfully. As Java and JavaScript have similar names, many newer developers often confuse the two. Java is a compiling language, meaning it’s translated into machine code by compilers. Alternatively, JavaScript is an interpreted scripting language, meaning it’s translated into machine code when it’s run. Before we explore everything you need to know to become a Java developer, you’ll need to understand what Java is.
Step 3. Join the Java Community to Learn From Your Peers
Java developers are responsible for developing software, websites, and applications using Java. New developers also confuse Java developers with software engineers, though these professions are different, too. Java developers are highly specialized professionals that (usually) only work with Java projects. A Java developer’s expertise lies in creating and managing applications powered by Java. As Java development requires redesigning and fixing code that isn’t working, a good developer can review their code, find errors, and fix problems quickly. When hiring a developer, look for someone who thrives on feedback and can demonstrate excellent creative problem-solving skills.
Since Java’s release in 1995, many modern programming languages have descended from it, including Python, Scala, JavaScript, and PHP. Naturally, Java has remained one of the most popular programming languages to learn. Remember, the Java programming language continuously evolves, with major updates occurring as frequently as four times each year. Keeping java developer education track of the latest releases will help you consistently align with industry best practices. Although not mandatory, acquiring knowledge through formal education, such as a college degree, can expedite learning. A common academic qualification among Java developers is a bachelor’s degree, with 75 percent of professionals holding this credential [6].

These may consist of Java development skills, code testing skills, SQL knowledge, project management skills, vendor liaison skills, and OOP knowledge. Soft skills help people succeed at work and include communication, problem-solving, and teamwork skills. To be an excellent full-stack Java developer, you need to learn Java and build your expertise in database management, object-oriented programming, and project management. You’ll also need excellent communication and problem-solving skills as Java developers solve technical issues with the rest of their business’s IT department.
- On the r/LearnJava subreddit, you’ll find Java resources, book recommendations, and posts from people looking for feedback on their code.
- Ideally, you should also familiarize yourself with Oracle 12c, Microsoft SQL, and MySQL database systems.
- Ideally, you should also develop your negotiation skills and build rapport with others, making liaising with vendors easier.
- Java is an Object-Oriented Programming (OOP) language, meaning it organizes design around objects (as opposed to functions and logic).

Someone Who Can Continue to Learn
Individual proficiency and collaborative teamwork can help you become a well-rounded Java developer. Working independently allows you to take ownership of tasks, manage your time effectively, and contribute your unique skills to projects. On the other hand, collaborating within a team creates an environment conducive to leveraging the strengths of each team member. Your proficiency in using Java testing tools, including Selenium, contributes to the creation of robust and dependable applications. By simulating real-world user scenarios using a separate database, you can uncover potential issues and rectify them before application deployment.
Alternatively, software engineers have a broader skillset to work on different programming languages and projects. As Java developers and software developers have similar roles and skills, many professionals transition between the two roles for variety, a new challenge, or to learn new skills. As you learn Java, you should also start improving your project management skills. During this step, you should focus on planning, designing, and building small-scale projects with Java. Managing small projects will help you develop your system architecture and management skills (as well as give you some projects to show potential employers during job interviews). As a feature-packed JavaScript library, jQuery helps you streamline your web development tasks, such as designing drop-down menus.
Java developer salary and job outlook
You should aim to create several Java applications for your portfolio (including at least one web application). These projects don’t have to be sophisticated or perfect, as they are simply a way for you to demonstrate that you can develop a range of applications with Java. As Java developers are highly skilled and perform diverse responsibilities, becoming a Java developer can earn a good salary. According to Salary.com, the average Java developer salary in the United States is $96,297 annually (as of October 29th, 2021). This means you will need to attend regular standups and meetings, help colleagues with problems, and help your team plan and manage your projects. You may also consult with users, managers, and other teams about your Java projects.
