JDBC (Java Database Connectivity) is an API (application programming interface) in the Java language for interacting with relational databases. It provides a set of classes and interfaces for executing SQL statements, accessing and managing databases. JDBC allows Java applications to communicate with various database systems (such as MySQL, Oracle, SQL Server, etc.) and is one of the standard ways to access databases on the Java platform.
JDBC provides a unified interface that allows developers to use the same code to interact with different databases without caring about the differences in the underlying databases. By using JDBC, developers can easily connect to the database, execute SQL queries and update statements, process transactions, and retrieve and modify data in the database.
The following is a simple Java program example that demonstrates how to use JDBC to connect to a database and perform query operations:
import java.sql.*;
public class JDBCDemo {
