Writing at the end of a file via opencsv

Question

I\'m using opencsv and want to write to a .csv file through multiple sessions. However every time I start a new CSVWriter the old file gets erased. Can I change

Answer 1

It doesn't seem possible to append to a file in opencsv (from an initial look, it looks rather simple), but if you're not restricted to opencsv you can try JExcel. To append to a file in JExcel you essentially need to create a copy then work off that, and overwrite the original. That could be similar in OpenCSV.

Edit: It seems like your only real option is to try out JExcel or read the entire file into a list, append to it, and write that out. If this is too heavy on memory, keep the stream open, read in chunks, write out chunks, then write out your appended chunk.
