Clean Java 7 way to create file if not exists [closed]

Question

What is the Java 7 or Java 8 way to create a file if that does not exists?

Answer 1

Not sure what you want, but for instance:

try {
    Files.createFile(thePath);
} catch (FileAlreadyExistsException ignored) {
}

And there are other solutions; for instance:

if (!Files.exists(thePath, LinkOption.NOFOLLOW_LINKS))
    Files.createFile(thePath);

Note that unlike File, these will throw exceptions if file creation fails! And relevant ones at that (for instance, AccessDeniedException, ReadOnlyFileSystemException, etc etc)
