In the world of Java programming and working with databases, becoming skilled in Java Database Connectivity (JDBC) is extremely important if you want to create strong and effective applications. To help Java learners get ready for interviews, we’ve put together a set of Multiple-Choice Questions (MCQs) that cover a wide range of JDBC topics.
These questions touch on the basics of connecting to databases, running SQL commands, and handling transactions, as well as more advanced subjects like connection pooling, managing result sets, and making the best use of resources with DataSource. Whether you’re just starting out and want to build a solid understanding of JDBC or you’re an experienced developer looking to refresh your skills, these MCQs will enhance your knowledge of JDBC, getting you ready for successful Java development interviews.
