宣布开始日期和结束使用乔达时间？

Question

我已经导入了joda libary，并且能够导入Easy Reader类。不过，我需要帮助格式正确，所以我可以计算在这之间的日子，是的，我与MM/dd/yyyy一起，但我使用了整数。我需要导入其他东西吗？我对乔达真的很陌生，所以请耐心等待，谢谢。一切似乎工作正常，但我找不到正确的语法，这将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

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

应该像

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

因为start和end已经LocalDate（多个） nd你想保存通话的结果。此外，您应该只需要一个EasyReader实例。并且，您需要添加

import org.joda.time.Days;
