What is Jdbc and how you connect Java with database?

JDBC mean Java Database Connectivity. In java, using JDBC drivers, we can connect to database.
Steps to connect to JDBC.
1) Load the driver, using Class.forName(DriverName);
2) Get the connection object, Connection con = Driver.getConnection(loaded driver name);
3) Create a SQL statement, Statement s = con.createStatement();
4) Create Resultset object using the statement created above, ResultSet rs = s.executeQuery("sql statement");

Iterate the result set to get all the values from the database.

Finally don't miss this
5) s.close();
6) con.close() ;
