我正在尝试计算两个小时之间的差异。时间格式必须是 hh:mm:ss！我实现了这个代码：

public static String timeDifference(long timeDifference1) {

    long timeDifference = timeDifference1 / 1000;
    int h = (int) (timeDifference / (3600));
    int m = (int) ((timeDifference - (h * 3600)) / 60);
    int s = (int) (timeDifference - (h * 3600) - m * 60);

    return String.format("%02d:%02d:%02d", h, m, s);
}

public static void main(String[] args) throws ParseException {
    Scanner sc = new Scanner(System.in);
    while (sc.hasNext()) {
        String timeStart = sc.next();
        String timeStop = sc.next();
        char lol[]=timeStop.toCharArray();
        if(lol[0]=='0' && lol[1]=='0'){ …
