Writing to a file and adding on

[Aziz]

When I write to a file, it erases the whole file, right? Is there a way to simply add to the end of a file? Or do I have to do something like this:\

(Psuedo:)

code:

while (!word == null) {      currentText += readLine() } newText = currentText + textToAdd println(newText)

Use the optional second boolean argument to the FileWriter constructor - set it to true to append to the file instead of truncating it.

To make it even easier, the Java API reference page on FileWriter.

I believe the reason it does that is becuase once u write to the file u arent closing the file (or the IO stream) if u close it it should work.. But its been a while so im not a hundred percent

Nope. The reason it's truncating the file is that you have to add the boolean append argument set to true for it to add to the file instead of truncate/write a new one.

Although, if he doesn't close (or flush, or checkError()) the stream, he won't get any data written at all.

Well, of course, I always (which means, usually, when I remember) call the close() method (at least I hope I did....*paranoid* let me double-check...)
