Java is still one of the most widely used programming languages today, despite its history and age. It makes sense that Java developers are in high demand! Look no further if you have a strong interest in technology and want to become a Java developer. The primary language of about 9 million developers worldwide is Java. Java was first created in 1995 by Sun Microsystems and has since developed into one of the most widely used programming languages in the software industry. It is consequently utilized to create applications spanning from software design and gaming technology to online and mobile applications since it is quick, safe, and dependable. Speaking in terms of programming concepts, Java is class-based, object-oriented, concurrent, and built upon foundational languages like C and C++. Java is hence very adaptable, coding-friendly, and in-demand as a skill-set. A java developer will be one of the most in-demand professions in 2023 because the majority of large corporations implement their software systems and backend services in Java.

A programmer that creates, creates, and manages Java-based software and applications is known as a Java Developer. Being a Java developer today is among the most in-demand professions because the majority of large firms use Java to construct software systems and backend services. Throughout the whole software development lifecycle, from concept and design to testing, a developer is in charge of several Java-related tasks. By developing, implementing, and maintaining Java-based components and interfaces, the developer is required to produce user information solutions. Java developers frequently collaborate closely with web developers, designers, and software engineers to produce fully integrated programs and applications for their clients. Java developers utilize their knowledge to create, modify, monitor, and repair software across a range of platforms.

Skills for Java Developer
Java developer abilities range widely, from having a solid grasp of the fundamentals to keeping up with the most recent advancements. Beyond the language itself, Java developers also need to have an understanding of the development process and the contexts in which the code is run. Having a Bachelor’s or Master’s degree in computer science or information technology with a concentration in software development is one of the main qualifications. Completion of a Core and Advanced Java-focused online or offline course is the second prerequisite. Additionally, the greatest approach to demonstrate the talents you have acquired is through projects and job experiences. This demonstrates both your linguistic proficiency and your ability to code on practical problems. Let us look into some basic skills needed for Java developers apart from the earlier said ones:
- Basic Java
You should take into account the following Java technologies if you want to be successful as a Java developer.Java is an object-oriented programming (OOP) language, hence it follows OOP principles. Relational databases like MariaDB, MySQL, and PostgreSQL. It will be useful to write MySQL queries. Technologies used for version control, including Git and BitBucket. Using an IDE such as IntelliJ IDEA for integrated development.HTML, CSS, and JQuery are examples of web frontend technologies.
- Supplementary language or technology
Different programming jobs are addressed by various frameworks and languages. Being fluent in multiple programming languages is crucial for this reason. Annual IT skills study from developer screening platform DevSkiller highlights extra technologies that Java developers pick up in addition to their primary language. Companies are searching for specialists with a Java + JavaScript stack as well as developers with experience in Java and SQL. In addition to the language they use, developers also operate in a certain setting. Therefore, Selenium, Android, Spring/Spring Boot, and JPA/Hibernate are among the most in-demand Java capabilities.
- Android and Kotlin
Many developers skip the web development stage and jump right into creating mobile apps. Your ability to create Android applications with Kotlin will set you out from the competitors. Kotlin, which is essentially a modified version of Java, is gradually replacing Java on the Android platform.
With one slight exception, this framework resembles a library. You can achieve your goal by calling the methods on objects of the classes using a library. Annotations are used by Spring to stray from tight connectedness, which occurs when classes directly depend on one another and interface from the same framework. The Model-View-Controller (MVC) structure, which separates the operations, business, and representation levels, is the foundation upon which Spring is currently built. Thanks to its excellent object injection features, beautiful syntax, simplicity, automation testing tools like JUnit 5, and minimal entry-level requirements even for Java beginners, Spring is well regarded by developers.
- Testing
Writing automated tests, such as unit and integration tests that demand the activation of an application, becomes increasingly difficult as your program expands. An application’s deployment and assembly take time in Java. Unit testing technologies like JUnit and TestNg come into use at that point. These frameworks facilitate the writing of automated tests, provide a simple syntax, and give you fast feedback on completed tests.
- SOLID Principles
Under the name SOLID: Single Responsibility Principle, Robert Martin (often referred to as Uncle Bob in the developer community) has defined five principles of object-oriented programming and design.
- Single Responsibility Principle
- Open closed Principle
- Liskov Substitution principle
- Interface Segregation principle
- Dependency Inversion Principle
These are the five principles of SOLID.
- DevOps Tools
DevOps expertise should be included among the top Java talents. Continuous integration (CI), continuous deployment (CD), and Jenkins’ role in both processes are concepts that any proficient developer should be familiar with. A thorough understanding of well-known DevOps tools like Docker, Chef, Kubernetes, Maven, and Jenkins is even more important for senior-level engineers whose duties frequently include applying coding best practices and producing manuals and scripts.
