Java is the most widespread programming language now, so it is becoming crucial to keep up with the trending tools and principal practices of Java. If you’re a Java developer and want to upskill in 2024 and coming 2025, let’s look at the basic skills to learn.
Java Framework Experience
- Spring and Hibernate still remain very important for the building of scalable, maintainable and secure applications.
- The microservices architecture depends on experience with Spring Boot.
Knowledge of Design Patterns
- Learning about design patterns such as Singleton, Factory and Observer would help developers build clean, reusable code.
Microservices and Cloud Computing
- Good Java developers need to know how everything works on the cloud platforms (AWS Azure) and how to build scalable and flexible microservices.
Database Knowledge
- You need expertise working with both SQL (MySQL, PostgreSQL) and NoSQL databases such as MongoDB for efficient storage and retrieval of data.
API Development Integration
- You will get to undertsand how to use RESTful APIs and use its integrations to third-party APIs using Spring Web or JAX-RS and how RESTful APIs create by refactoring a website into one using the REST APIs.
Continuous Integration (CI/CD) and DevOps
- If someone knows CI/CD toolsets (Jenkins, Git Lab CI) and containerisation platforms (Docker, Kubernetes), then you can enhance your development and deployment pipeline-building experience.
Testing and Quality Assurance
- A code reliability guarantee depends on unit testing (e.g., JUnit, Mockito) and integration testing.
Concurrency and Multithreading
- The fundamental capability of creating high-performance applications is handling concurrency with threads, ExecutorService, and CompletableFuture.
Security Best Practices
- It is important for security awareness as everything has been moving towards security awareness, from data encryption to authentication and authorisation mechanisms (OAuth, JWT).
Soft Skills and Communication
- Developers need strong problem-solving, collaboration, and communication skills to work effectively with fellow developers in agile teams and with clients.
