Mastery in these devices will make you more efficient in writing, testing and deploying Java applications.
Explore Java Frameworks
Java Framework simplifies the development process. Some popular framework includes:
- Spring Boot: For the building of enterprise applications.
- Hibernate: For database connectivity using ORM (Object-Religious Mapping).
- Straits: For web application development.
- Java Server FACES (JSF): User is used for the building of user interfaces for Java applications.
Understanding these frameworks will help you build scalable and maintainable applications.
Learn Database Management
Java applications often interact with the database. Learn:
- SQL: MySQL, PostgreSQL, or Oracle Database.
- NoSQL: MongoDB or Cassandra.
- JDBC (Java Database Connectivity): Connecting Java applications to the database.
It is necessary to have strong database management skills for backend development.
Work on Real Projects
The Building of real -world projects enhances your skills and adds value to your resume. Some initial-friendly projects include:
