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:)

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...) |
