import java.sql.*; import java.io.*; import java.util.*; public class CallBill { public static void main(String args[])throws SQLException,IOException {

DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","vinni","vickyjasti"); Statement stmt=con.createStatement(); String squery="select * from customer"; System.out.println(squery); ResultSet rs=stmt.executeQuery(squery);

while(rs.next()) {

 int no=rs.getInt(noc);
 double bamt=no*.50;
 String uquery="update customer set bamt=? where pno=?";
 System.out.println(uquery);
 PreparedStatement pstmt=con.prepareStatement(uquery);
 pstmt.setDouble(1,bamt);
