How do I find the last modified file in a directory in java?

Answer 1

Java 8

Optional findLastModifiedFile(Path directory) throws IOException {
    return Files.list(directory)
            .max(this::compareLastModified);
}

int compareLastModified(Path p1, Path p2) {
    try {
        return Files.getLastModifiedTime(p1).compareTo(Files.getLastModifiedTime(p2));
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}
