sort array column 5

Show all headers | View raw

Hi, 
I'm scripting a java program that sort descending data from csv file

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintStream;
import java.util.Arrays;


public class javaRes {

// Sort column csv

 static class OrderColumn

 {
     public static void main (String[] args) throws IOException

     {
         File fileCSV = new File("Analisi_2018.csv");
         BufferedReader streamCSV = new BufferedReader(new FileReader(fileCSV));

         //Instantiating the File class
      File file = new File("provvi.csv");
      //Instantiating the PrintStream class
      PrintStream stream = new PrintStream(file);
      System.setOut(stream);

         String lineRead;
         
         int tmpRowCount=0;

         while( (lineRead=streamCSV.readLine()) != null )
         {
             tmpRowCount++;
         }

         streamCSV.close();

         System.out.println("Rowcount= "+tmpRowCount);

         String[] fileArray=new String[tmpRowCount];

         streamCSV = new BufferedReader(new FileReader(fileCSV));

         int tmpI=0;

         while( (lineRead=streamCSV.readLine()) != null )

         {

             fileArray[tmpI++]=lineRead;

         }
         //SORT HERE


    Arrays.sort(fileArray, Collections.reverseOrder());

     for (String number : fileArray) {
        System.out.println(number);
     }

   

         System.exit(1);

     }

 }

}

I obtain a new .csv 
but sorting about column 1
I would order with target column 6
How could fix it using this scheme of program 

regards

A
