its a text file, what would i change if i am given an object of type java.io.File instead of the FileOutputStream?

Nothing, except that you stick the file instead of the stream into a FileWriter's c'tor.

I can not see you code. I have no idea what it looks like. As such, I can not make suggestions on what to change.

I can take a guess if you like.

You currently have code like:

public void writeDaLetters( OutputStream s ) { .. }

Well, add a second method which takes a File. In this method open a FileOutputStream, and pass it to the writeDaLetters( OutputStream s ) method.

Next time please give your thread a meaningful subject line. "need some help for questions" tells us nothing, and the exclamaiton points are simply annoying.
