Read CSV 

Super CSV is a free library for reading and writing CSV files in Java. We need to have SuperCSV-1.52.jar, spiffy-0.05.jar or later versions in classpath. The following example shows reading a CSV file line by line using Super CSV.

  • test1.csv
    aaaa,bbbb,cccc,dddd
    one,two,three,four

package com.bethecoder.tutorials.super_csv.tests;

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

import org.supercsv.io.CsvListReader;
import org.supercsv.prefs.CsvPreference;

public class ReadCSV {

  /**
   @param args
   @throws IOException 
   */
  public static void main(String[] argsthrows IOException {
    /**
     * Load CSV from classpath
     */
    CsvListReader csvReader = new CsvListReader(new InputStreamReader(
        ReadCSV.class.getClassLoader().getResourceAsStream("test1.csv")),
        CsvPreference.STANDARD_PREFERENCE);
    
      List<String> rowAsTokens;
      while ((rowAsTokens = csvReader.read()) != null) {
        System.out.print("Row#" + csvReader.getLineNumber() " ");
        for (String token : rowAsTokens) {
          System.out.print(token + " ");
        }
        System.out.println();
      }
  }

}
   

It gives the following output,
Row#1 aaaa bbbb cccc dddd 
Row#2 one two three four 


                    Print
