FileWriter.writeln(String)

I would like a method in FileWriter that adds the system-dependent linebreak character after the line: .writeln(String). As FileWriter inherits its write methods from OutputStreamWriter and Writer, it should probably be defined in one of these.
Yeah, I could use PrintWriter, but there are more differences to PrintWriter than that it has println methods, e.g. it does not throw Exceptions, but sets an error flag, so I would really prefer if FileWriter had a writeln method.
So far I do write(String + BR) and have static String BR = System.getProperty("line.separator"); in the class. It's okay, but a writeln method would be nicer.
Monika.

No, you should wrap FileWriter in a BufferedWriter which already has a newLine() method. Perhaps some writeln convenience methods should be added to BufferedWriter.

So, add writeln to java.io.Writer, then both BufferedWriter and FileWriter will have it.

Have you noticed that since 1.5 Writer has mentioned chained method Writer append(CharSequence csq) & friends?
Still, java.io.Writer is the best place for something like writeln() or newLine()...

I think it is much better to use BufferedWriter which has newLine() method doing what you need. And it performs much better of course. However, println() still missing 
Anyway, I would prefer some implementation that behaves the similar way as StringBuffer or StringBuilder and allows chained calls (append().append().append()...)

Yes, and use this 'pattern' anywhere it is possible, for example Collection's add().add() ... Map's put().put()... etc.

I mentioned in my original post why I do not want to use it.
