Own CSV Parser : This examples shows how to create a your own CSV parser.

This example
  i) Reads a CSV File as Stream
  ii) Parses Data and create String[][]

         int nLine = lineList.size();
         int nRealLine = nLine-nHeaderLine;
         if (nRealLine<=0) return null;
         String [][] fields = new String [nRealLine][];
        
         Iterator iter = lineList.iterator();
         for (int i=0; i<nHeaderLine;i++){
             iter.next();
         }
        
         for (int i=0; i<nRealLine; i++){

         }
        
         return fields;
