Reading Long data from CSV

I have a CSV file, I'm reading it the elements from the file

each line is converted to List, one of the columns is a long data, but Java reads it in

2.01005E+14 format, and I cannot convert it to long, Is there a way to convert only that value to long?

The is the value in the CSV 201005300149580.

The code, my CSV class

 package com.gta.moneyb.util;

import java.util.ArrayList;
import java.util.List;

public class CSV {

   public static final char DEFAULT_SEP = ',';

   /** Construct a CSV parser, with the default separator (`,'). */
   public CSV() {
     this(DEFAULT_SEP);
   }

   /** Construct a CSV parser with a given separator. 
    * @param sep The single char for the separator (not a list of
    * separator characters)
    */
   public CSV(char sep) {
     fieldSep = sep;
   }

   /** The fields in the current String */
   protected List<String> list = new ArrayList<String>();

   /** the separator char for this parser */
   protected char fieldSep;

   /** parse: break the input String into fields
    * @return java.util.Iterator containing each field 
    * from the original as a String, in order.
    */
   public List<String> parse(String line)
   {
     StringBuffer sb = new StringBuffer();
     list.clear();      // recycle to initial state
     int i = 0;

     if (line.length() == 0) {
       list.add(line);
       return list;
     }

     do {
             sb.setLength(0);
             if (i < line.length() && line.charAt(i) == '"')
                 i = advQuoted(line, sb, ++i);  // skip quote
             else
                 i = advPlain(line, sb, i);
             list.add(sb.toString());
       i++;
     } while (i < line.length());

     return list;
   }

   /** advQuoted: quoted field; return index of next separator */
   protected int advQuoted(String s, StringBuffer sb, int i)
   {
     int j;
     int len= s.length();
         for (j=i; j<len; j++) {
             if (s.charAt(j) == '"' && j+1 < len) {
                 if (s.charAt(j+1) == '"') {
                     j++; // skip escape char
                 } else if (s.charAt(j+1) == fieldSep) { //next delimeter
                     j++; // skip end quotes
                     break;
                 }
             } else if (s.charAt(j) == '"' && j+1 == len) { // end quotes at end of line
                 break; //done
       }
       sb.append(s.charAt(j));  // regular character.
     }
     return j;
   }

   /** advPlain: unquoted field; return index of next separator */
   protected int advPlain(String s, StringBuffer sb, int i)
   {
     int j;

     j = s.indexOf(fieldSep, i); // look for separator
         if (j == -1) {                 // none found
             sb.append(s.substring(i));
             return s.length();
         } else {
             sb.append(s.substring(i, j));
             return j;
         }
     }
 }

The problem is with the CSV file, I created a CSV file in Notepad with the above values and they come up fine
