CSV produces a number

Question

since I didn't get any conclusion from this thread, I decided to open a new one.
[ref: http://forum.java.sun.com/thread.jspa?threadID=5194217]
I have a CSV file in which I would like to write the STRING 0607 but for some reason the output comes as: 607
Does anyone know any CSV API that state that the value is a STRING and not a NUMBER?
thanks
Code:
     public static void produceCSVjv(String path, String fileName) throws IOException
          FileWriter writeCSV = new FileWriter(path+"/"+fileName);
          PrintWriter fileOutput = new PrintWriter(writeCSV);     
          fileOutput.println("\"0607 \"");  //result 607
                fileOutput.println("0607"); //result 607
          fileOutput.close();          
     }

import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;
public class CSV
     public static void main(String args[]) throws IOException
          PrintWriter fileOutput = new PrintWriter(new FileWriter("testMyCsv.csv"));     
          fileOutput.println("\"0607\"");
          fileOutput.println("0607");
          fileOutput.close();     
}
