RandomAccessFile raf = new RandomAccessFile("somefile", "rw");
raf.setLength(0);
raf.close();

or

(new FileOutputStream("somefile")).close();

or

File f = new File("somefile");
if (f.exists()) {
f.delete();
}
f.createNewFile();

Thanks for your answer. I should have specified that the file
"somefile" already exists but I don't care about its contents, I just
need to empty it.

Did you try the suggestions above? I think they would work despite this
extra specification.

Yes, I tried them, and they work as expected.

Thanks!
