What should I do after learning Java core?

After mastering Java core, consider expanding your skills by exploring more advanced Java topics such as: Object-Oriented Programming (OOP): Deepen your understanding of OOP principles and design patterns. Java Collections Framework: Learn about various data structures and algorithms provided by Java for efficient data manipulation. Multithreading and Concurrency: Understand how to work with multiple threads to improve program performance. Java I/O and Networking: Explore handling input/output operations and network programming. Database Connectivity: Learn about JDBC for connecting Java applications to databases. GUI Development: Explore JavaFX or Swing for creating graphical user interfaces. Web Development: Start with Servlets and JSP for server-side web development, or move on to frameworks like Spring. Spring Framework: Gain proficiency in this popular framework for building enterprise-level Java applications. Hibernate or JPA: Understand ORM (Object-Relational Mapping) for database interactions. Build Tools and Version Control: Familiarize yourself with tools like Maven or Gradle and version control systems like Git. Unit Testing: Learn testing frameworks like JUnit for ensuring code quality. Web Services: Explore building and consuming RESTful APIs. Maven or Gradle: Understand how to manage project dependencies and build processes. Continuous Integration and Deployment (CI/CD): Learn how to automate testing and deployment processes. Cloud Technologies: Explore cloud platforms like AWS, Azure, or Google Cloud for deploying and scaling Java applications. Remember to practice what you learn by working on projects or contributing to open-source projects. This hands-on experience will deepen your understanding and make you a more proficient Java developer. read less

After mastering Java core concepts, consider diving into advanced topics like multi-threading, databases (JDBC), frameworks like Spring or Hibernate, and design patterns. Explore web development with Java EE or Spring Boot. Enhance your knowledge of data structures, algorithms, and best practices. Build projects to apply what you've learned, contribute to open-source projects, and consider certifications to validate your skills. Additionally, expand your horizons by learning related technologies like version control systems (Git), containerization (Docker), and cloud services (AWS, Azure) to become a well-rounded Java developer ready for real-world applications.
