The world’s most popular modern development platform, Java SE is the programming language of choice for enterprise applications. Java SE reduces costs, shortens development time, drives innovation, and improves application services. Protect your Java investment with Oracle Java SE Universal Subscription, which now includes Oracle GraalVM and Java Management Service. It reduces costs, shortens development timeframes, drives innovation, and improves application services. With millions of developers running more than 60 billion Java Virtual Machines worldwide, Java continues to be the development platform of choice for enterprises and developers. However, most employers require applicants to have a degree in computer science, information systems, mathematics, or any other related field.
A key task for backend developers is designing and implementing database structures that hold application data securely, while ensuring they perform efficiently. Java-based technologies such as Java Persistence API (JPA) and Hibernate simplify the development process and make it easy to manage different database systems. The role of a Java backend developer extends to creating and linking different layers, including the web server, application server, and database.
Software Engineer (Development)- Early Career
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 java developer course to show potential employers during job interviews). 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.
- Spring Framework is a comprehensive framework for developing Java applications.
- According to Stack Overflow, the average Java salary worldwide in 2022 was almost €58,000 a year.
- However, most employers require applicants to have a degree in computer science, information systems, mathematics, or any other related field.
- Understanding these terms will allow Java developers to navigate through the development process smoothly, enabling them to build efficient, robust, and scalable applications.

Someone Who Can Continue to Learn
Stop wasting time with fruitless job searches and use our job board instead. You should also familiarise yourself with the Java Development Kit (JDK), the Java Runtime Environment (JRE), and the Java Virtual Machine (JVM). JDBC (Java Database Connectivity) and JPA (Java Persistence API) are among the essential tools you need to know. It can be used to create server-side applications, mobile apps, and games, or to equip home appliances with basic features. Users choose it for web development, mobile development (especially for Android apps with Kotlin), desktop applications, embedded systems, and big data processing, and more.
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). GraalVM for JDK 21 will receive updates under the GFTC, until September 2026, a year after the release of the next LTS. JDK 21 will receive updates under the NFTC, until September 2026, a year after the release of the next LTS. Subsequent JDK 21 updates will be licensed under the Java SE OTN License (OTN) and production use beyond the limited free grants of the OTN license will require a fee. Take advantage of the high-performance JDK with advanced optimizations that improve Java application performance and microservices deployment—on-premises and in the cloud.

According to 2021 data, experience effectively impacts salaries in Germany. JPA (Java Persistence API) is a Java specification for accessing, persisting, and managing data between Java objects and a relational database.
Java Platform, Standard Edition (Java SE) lets you develop and deploy Java applications on desktops and servers. In summary, Java backend development involves a range of specialised tasks that require technical expertise and knowledge of the Java ecosystem. It’s true that many of the tasks overlap with those of backend developers — but that’s because Java can be used for backend. A Java developer https://deveducation.com/ is a programmer with a solid understanding of Java syntax, object-oriented programming principles, and software development best practices. Java developers use various tools, libraries, and frameworks to create software solutions for different industries, even for software engineers or web developers. As you learn Java, you should also start improving your project management skills.
