Today's snippet from Rich D is short and sweet, and admittedly, not the most TFs of WTFs out there. But it made me chuckle, and sometimes that's all we need. This Java snippet shows us how to delete a file:
if (Files.exists(filePath)) {
Files.deleteIfExists(filePath);
}
If the file exists, then if it exists, delete it.
This commit was clearly submitted by the Department of Redundancy Department. One might be tempted to hypothesize that there's some race condition or something that they're trying to route around, but if they are, this isn't the way to do it, per the docs: "Consequently this method may not be atomic with respect to other file system operations." But also, I fail to see how this would do that anyway.
The only thing we can say for certain about using deleteIfExists instead of delete is that deleteIfExists will never throw a NoSuchFileException.
