Coding a JDBC Connection

You can establish a database connection in pure JDBC code.

To code a JDBC Connection:

Import the JDBC classes using the statement
```
import java.sql.*;
```
This statement is required for all JDBC programming.

DriverManager.registerDriver
    (new oracle.jdbc.driver.OracleDriver());

Get a connection to a data server using the statement calling one of the getConnection methods:
```
Connection conn = DriverManager.getConnection(parameters...);
```
There are three driver manager getConnection methods, differing in the number and types of their parameters.
