DriverManager class

By / 18 August 2026 / 2 minutes of reading

The DriverManager class belongs to the java.sql package and is responsible for managing JDBC drivers. It acts as an important component between a Java application and the JDBC drivers. The DriverManager selects an appropriate JDBC driver based on the database URL provided by the application. It is mainly used to establish a connection with a database using the getConnection() method. It also provides methods for registering, deregistering, and retrieving JDBC drivers.
