使用 Joda Time 声明开始日期和日期？

Question

我已经导入了joda库，并且能够导入Easy Reader类。但是，我需要帮助正确格式化，以便我可以计算中间的天数，是的，我使用 MM/dd/yyyy，但我使用了整数。我需要导入其他内容吗？我是乔达的新手，所以请耐心等待，谢谢。一切似乎都很好，但我找不到正确的语法来帮助我找到两个日期之间的差异，而且我找不到它。

import org.joda.time.DateTime;
import org.joda.time.DateTimeZone;
import org.joda.time.LocalDate;
class starter{
public static void BdayPrgm(String args[]){
System.out.println("Please Enter Today's Month: ");
EasyReader month = new EasyReader();
//this will indentify it as an INT, not a string.
//quest is a question btw.
todaysmon = month.readInt();
System.out.println("What number is today?: ");
EasyReader currentday = new EasyReader();
todayday = currentday.readInt();

System.out.println("What is today's year?: ");
EasyReader todayyear = new EasyReader();
year = todayyear.readInt();
System.out.println("");
System.out.println("What is your BdayMonth?: ");
EasyReader thatyear = new EasyReader();
bdaymon = thatyear.readInt();
System.out.println("What is your Bday #?: ");
EasyReader thatday = new EasyReader();
thatgr8day = thatday.readInt();
System.out.println("What is the bdayyear?: ");
EasyReader bdayyear = new EasyReader();
bdayyr = bdayyear.readInt();

int age;
age = year - bdayyr;

//we can get start date by putting test maybe?
DateTimeZone LA = DateTimeZone.forID("America/Los_Angeles");
LocalDate start = new LocalDate(year,todaysmon,todayday);
LocalDate end = new LocalDate(year,bdaymon,thatgr8day);
int Days;
//code isn't compileing below. I don't know what I'm doing wrong.
Days.daysBetween(new LocalDate(start),new LocalDate(end)).getDays();
//int days = d.getdays;
System.out.println("");
System.out.println(CELEB1+" is going to be "+age+" years old in X days!");

}

}

Answer 1

int Days;
Days.daysBetween(new LocalDate(start),new LocalDate(end)).getDays();

应该是这样的

int dayCount = Days.daysBetween(start, end).getDays();

因为start和end已经LocalDate，并且您希望保存呼叫结果。此外，您应该只需要一个EasyReader实例。而且，您需要添加

import org.joda.time.Days;
