Here is my code</p> <pre><code>package csv; import java.io.IOException; import au.com.bytecode.opencsv.CSVReader; import java.io.FileReader; import csv.*; import java.io.*; public class CSVParser { public static void main(String[] args) throws IOException,java.io.FileNotFoundException { try{ CSVReader reader = new CSVReader(new FileReader("D:\\error.txt")); String sLine = null; String[] nextLine; int count=0,flag=0; nextLine=reader.readNext(); while( (nextLine!=null) ) { count++; System.out.println("count::: "+count + "and length is" +nextLine.length); System.out.println("String:::"+nextLine[0]); if ( (nextLine.length!= 9) ) { flag=1; break; } nextLine=reader.readNext(); } System.out.println("No of lines:::"+count); if(flag==1) { reader.close(); System.out.println("errror"); movefiles m= new movefiles(); m.move("D:\\error.txt"); } else{ System.out.println("No error"); try{ while((nextLine=reader.readNext())!=null) { String code = nextLine[0].toString(); String commodity = nextLine[1].toString(); float contract_price = Float.parseFloat(nextLine[2].toString()); float open_contract_vol = Float.parseFloat(nextLine[3].toString()); float open_contract_price = Float.parseFloat(nextLine[4].toString()); float unpriced_vol = Float.parseFloat(nextLine[5].toString()); float holdover_prod = Float.parseFloat(nextLine[6].toString()); String date = nextLine[7].toString(); String time = nextLine[8].toString(); System.out.println("Data From File is :::" + code +commodity +contract_price +open_contract_vol +open_contract_price +unpriced_vol +holdover_prod +date +time); }}catch(Exception e) { e.printStackTrace(); System.err.println("here is error:::"+e.getMessage()); } } reader.close(); } catch(Exception e) { e.printStackTrace(); System.err.println("error:::" +e.getMessage()); } } } </code></pre> <p>But problem is when i run this code even if my file contains one line it shows two lines and second line doesn't contain anything.

    1. CODid you manually type this code into the question (its not compilable)? I see at least two problems in your code but will not mention them because it may be typos when you transcribed the question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
