jdbc is an API provided to connet various DB's from a java

avilable to connect DB.

driver.

Class.forName("Oracle.jdbc.driver.OracleDriver");

String url="jdbc:oracle:thin:@localhost:1521:server";

Connection connection=DriverManager.getConnection
(url,"SCOTT","TIGER");

PreparedStatement ps=connection.prepareStatement("SELECT *
FROM EMPLOYEE");

ResultSet rs=ps.executeQuery();
