Java input / output: how to add to an existing text file

Question

Hi, I have no problem writing or adding to the file, the only problem is that as soon as I quit the program and then run it again, it will create a new file overwriting my original file. This is a problem as I use a text file to save the current table.

Is there a way to get an already created text file as an object and then add to it?

Thanks in advance.
