使用 joda 时间声明开始日期和结束日期？ [复制]

Question

我已经导入了 joda 库，并且能够导入 Easy Reader 类。但是，我需要正确格式化的帮助，以便我可以计算两者之间的天数，是的，我熟悉 MM/dd/yyyy，但我使用了整数。我需要导入其他东西吗？我是joda的新手，所以请耐心等待，谢谢。一切似乎都正常，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，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

这个

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 已经是LocalDate(s) 并且您想保存调用的结果。此外，您应该只需要 一个 EasyReader instance。而且，您需要添加

import org.joda.time.Days;
