Difference between PrintWriter and FileWriter class

Question

try{

    File file = new File(\"write.txt\");
    FileWriter writer = new FileWriter(file);

    PrintWriter printWriter = new PrintWriter(writer);
    printWriter.prin         


        

Answer 1

From the source what PrintWriter does when you pass a File is to open it in a buffered way

public PrintWriter(File file) throws FileNotFoundException {
    this(new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file))),
         false);
}

if you pass it a FileWriter, it will open it, without buffering

public FileWriter(File file) throws IOException {
    super(new FileOutputStream(file));
}

This means that the first example can be slightly more efficient. However I would use the File without the FileWriter because to me it is simpler.
