找出java.util.Date和Joda-Time DateTime之间的天数差异？

Question

是否有可能找到a java.util.Date和Joda-Time 之间的差异(最好以天数表示)DateTime？

class ReminderInterval{
    //it will return a last login date(java.util.Date)
    Date lastDate=Obj.getAccepted();

    //it is Joda-Time type
    DateTime currentDate=new DateTime();
}

Answer 1

只需转换Date为DateTime然后使用Days#daysBetween().该DateTime有一个构造函数抽出时间以毫秒和Date具有吸气返回exaclty说.

DateTime lastDate = new DateTime(Obj.getAccepted().getTime());
DateTime currentDate = new DateTime();
int days = Days.daysBetween(lastDate, currentDate).getDays();
