Answer 1

Since File is a bad abstraction, it is better to use Files and Path:

public static void touch(final Path path) throws IOException {
    Objects.requireNotNull(path, "path is null");
    if (Files.exists(path)) {
        Files.setLastModifiedTime(path, FileTime.from(Instant.now()));
    } else {
        Files.createFile(path);
    }
}
