what is the difference between these two ways of writing to a file in java?

I have two implementations below, where the PrintStream object wraps either FileOutputStream object or File object. I get the same thing done with both. Are there any difference between them where one method will not be applicable to write.

public class Varags {
        public static void main(String[] args) throws FileNotFoundException{

            OutputStream output = new FileOutputStream("Test.txt");
                         PrintStream p1=new PrintStream( output);
                         p1.println("trying");

            PrintStream p=new PrintStream( new File("test2.txt"));
            p.println("trying");
}
}

Are there other way of writing to file that is better than these?

Thanks

As far as I know there is no difference. According to the Javadocs the File version creates an OutputStreamWriter anyways, and is only included for convenience.

In many cases, using a Writer is better for plain text input. If you're working with raw byte data then streams such as FileInputStream, FileOutputStream, etc. will be necessary.

PrintStream provides some convenience methods for writing text to a file. To get more control about writing characters to a file, use PrintWriter.

OutputStream is used to write bytes (pure data, not just text) to a file.
