The following steps are required connect/select the Database JDBC application −

• Import the packages: Requires that you include the packages containing the JDBC classes needed for database programming. Most often, using import java.sql.* will suffice.
• Register the JDBC driver: Requires that you initialize a driver so you can open a communications channel with the database.
• Open a connection: Requires using the DriverManager.getConnection() method to create a Connection object, which represents a physical connection with a database server.
• Execute a query: Requires using an object of type Statement for building and submitting an SQL statement to select (i.e. fetch ) records from a table.
• Extract Data: Once SQL query is executed, you can fetch records from the table.
• Clean up the environment: Requires explicitly closing all database resources versus relying on the JVM's garbage collection.

You will get lot of example in online but all should have above steps in the program.

Note that you do not have to register a driver anymore. The practice of using Class.forName to load and register JDBC drivers has been obsolete for a very long time now. All up-to-date JDBC drivers register themselves automatically.
