您可以尝试以下代码：

    Calendar calendar = Calendar.getInstance(Locale.getDefault());
    int hour = calendar.get(Calendar.HOUR_OF_DAY);
    int minute = calendar.get(Calendar.MINUTE);

System.currentTimeMillis()

You can use this function to escape creation of date object.

您可以使用此函数来逃避日期对象的创建。

You can persist it as long and you always can create Date object of it.

你可以坚持多久，你总是可以创建它的 Date 对象。
