    File file = new File("filename");
    
    // Get the last modified time
    long modifiedTime = file.lastModified();
    // 0L is returned if the file does not exist
    
    // Set the last modified time
    long newModifiedTime = System.currentTimeMillis();
    boolean success = file.setLastModified(newModifiedTime);
    if (!success) {
