2. Java Frameworks and Libraries
- Spring Framework: Spring is a popular and powerful Java framework that provides a comprehensive set of features for building enterprise-scale applications. Spring makes it easier to develop loosely coupled, modular applications and reduces boilerplate code.
- Hibernate: Hibernate is an object-relational mapper (ORM) that simplifies the interaction between Java applications and relational databases. Hibernate maps Java classes to database tables and handles the underlying SQL queries for you.
- Other Frameworks and Libraries: There are many other popular Java frameworks and libraries available, such as Struts, JUnit, and Mockito. The specific frameworks and libraries you’ll need to learn will depend on the type of applications you’re developing.
3. Additional Skills
