Read a text file then write it with the same name

Question

Hello
I have to read a file (.cvs file) then change a value of a field in it and save it again. Therefore, the read file and the write file is the same name. I use CVSParse for doing this
Here is my code:
private void updateClassName(String className, String fileName) throws IOException{
          String[][] values=new String[0][0];
          FileReader fileReader = new FileReader(fileName);
     BufferedReader in = new BufferedReader(fileReader);
          values = CSVParser.parse(in);
          List lines = new ArrayList();
          for (int i=0; i<values.length; i++){
               values[2]= className;
               lines.add(values[i]);
          try{
               CSVPrinter cp=new CSVPrinter(new FileOutputStream(fileName));
               Iterator i=lines.iterator();
               while (i.hasNext()){
                         String[] line=(String[]) i.next();
     cp.writeln(line);
     cp.close();
     catch (IOException e)
     logger.error(e.getStackTrace());
     logger.info("ERRORS: CANNOT WRITE INTO FILE");
It it OK when the read file and the write name is the same?
It is OK with the code above?
Many thanks

Sorry
I post the code again:
<code>
private void updateClassName(String className, String fileName) throws IOException{
String[][] values=new String[0][0];
FileReader fileReader = new FileReader(fileName);
BufferedReader in = new BufferedReader(fileReader);
values = CSVParser.parse(in);
List lines = new ArrayList();
for (int i=0; i<values.length; i++){
values[2]= className;
lines.add(values);
try{
CSVPrinter cp=new CSVPrinter(new FileOutputStream(fileName));
Iterator i=lines.iterator();
while (i.hasNext()){
String[] line=(String[]) i.next();
cp.writeln(line);
cp.close();
catch (IOException e){
