Trying to copy file from one location to another

Question

Hello I'm trying to copy file to another directory with commons fileUtils. I tried this

FileUtils.copyFile(getOutputFile(), new File("RESULT/final_result.txt");

The new final_result.txt file contains only the first line of my output file, what did I do wrong?

Is there an alternative to commons IO, or some other way I'll take any as long as it does the trick.

Answer 1

first, it seems you forgot to close the parenthesis containing the method's arguments. second, are you sure getOutputFile() yields a complete file?

Answer 2

Try new File(Result,"final_result.txt");
Result should be of type File and final_result.txt String

Answer 3

if you write file (which you get by getOutputFile()) before this operation, be sure to flush() all changes.
Otherwise it seems to be a bug. But it is unlikely.

Answer 4

Perhaps you need to do a simple test using a debug or sleep:

1. manually delete RESULT/final_result.txt
2. run the code that creates your output file and either sleep, or use a breakpoint with debugging to stop after the files is created.
3. Manually open RESULT/final_result.txt and see what's there.
4. let your program finish it's task.

You'll either find that your write is not complete (in step 3) and you'll need to flush/close the correct ouput stream, or you'll find that the copy is doing something weird (which is less likely).
