Functions of the jdbcHelloWorld.java programAlthough jdbcHelloWorld.java is a simple program, it illustrates severalimportant functions:♦♦♦♦Imports the necessary Java classes, including JDBC classesRegisters the JDBC driverConnects to the databaseExecutes a simple query♦ Outputs the query results to your screenFor detailed information on these functions, see "First steps in JDBC" onpage 20.Example of the jdbcHelloWorld.java programThe following is a listing of jdbcHelloWorld.java for the JDBC driver://// This example demonstrates a simple JDBC application.//// This sample can be used to check the JDBC installation.// Run the application and provide connection information for// a demo/jdbc/samples/ Database that you have access to. It will select// and display "Hello World" from the database.//import java.io.*;//// You need to import java.sql package to use JDBC//import java.sql.*;class jdbcHelloWorld {public static void main (String args []) throws SQLException, IOException{// Load the JDBC driverDriverManager.registerDriver(new ordbjava.jdbc.ordbDriver());// Prompt the user for connect informationJDBC Developer's Guide, P25-9504-03 Page 16Chapter: 2.
