Java JDBC Programs - Basic to Advanced

This article provides a variety of programs on JDBC, that are frequently asked in the technical round in various Software Engineering/JAVA Backend Developer Interviews including various operations such as CREATE, INSERT, UPDATE, DELETE and SELECT on SQL Database etc. Additionally, all programs come with a detailed description, Java code, and output.

Just like in many other programming languages, there is a specialized library available for executing CRUD operations (Create, Read/Retrieve, Update and Delete) when working with databases. Similarly, In Java, We have JDBC, an API (application programming interface) used in Java programming to interact with databases. The classes and interfaces of JDBC allow the application to send user requests to the specified database.
