How Jdbc program can be run??

import java.sql.*; import java.util.*; class MyDbCode3 {

public static void main(String [] args) { try { Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); } catch(ClassNotFoundException cnf) { System.out.println("Cannot load the Driver"); System.exit(1); } Scanner kb=new Scanner(System.in); int id; System.out.println("Enter bookid:"); id=kb.nextInt(); try { Connection conn=DriverManager.getConnection("jdbc:odbc:advdsn1","student","myself"); Statement st=conn.createStatement(); String qry="Update mybooks set price=price+1000 where bookid="+id; System.out.println(qry); int x=st.executeUpdate(qry); System.out.println("Rows effected="+x); conn.close(); } catch(SQLException sq) { System.out.println("Sql Error:"+sq.getMessage()); } } }
