Most efficient way to check if a file is empty in Java on Windows

Question

I am trying to check if a log file is empty (meaning no errors) or not, in Java, on Windows. I have tried using 2 methods so far.

Method 1 (Failure)

Answer 1

Another way to do this is (using Apache Commons FileUtils) -

private void printEmptyFileName(final File file) throws IOException {
    if (FileUtils.readFileToString(file).trim().isEmpty()) {
        System.out.println("File is empty: " + file.getName());
    }        
}
