File truncate operation in Java

Question

What is the best-practice way to truncate a file in Java? For example this dummy function, just as an example to clarify the intent:

void readAndTruncate(Fil         


        

Answer 1

One liner using Files.write()...

Files.write(outFile, new byte[0], StandardOpenOption.TRUNCATE_EXISTING);

Can use File.toPath() to convert from File to Path prior as well.

Also allows other StandardOpenOptions.
