Package org.evolvis.tartools.csvfile

Class CSVFile

java.lang.Object
org.evolvis.tartools.csvfile.CSVFile
Direct Known Subclasses:
CSVFileReader, CSVFileWriter
public abstract class CSVFile extends Object
CSVFile is a Java™ class used to handle comma-separated value files. It is an abstract base class for CSVFileReader and CSVFileWriter, so you should use one of these (or both), according on what you need to do. The simplest example for using the classes contained in this package is the following example that simply converts one CSV file into another one that makes use of a different notation for field separator and text qualifier (quote character). It just comprises the following lines: 
 package org.evolvis.tartools.csvfile;

 import java.io.IOException;
 import java.util.List;

 public class CSVFileExample {
     public static void main(String[] args) throws IOException {
         CSVFileReader in = new CSVFileReader("csv_in.txt", ';', '"');
         CSVFileWriter out = new CSVFileWriter("csv_out.txt", ',', '\'');

         List fields = in.readFields();
         while (fields != null) {
             out.writeFields(fields);
             fields = in.readFields();
         }

         in.close();
         out.close();
     }
 }
