獲取java中兩個日期之間的天數

Question

您好日期格式有兩個日期，我如何得到兩個日期之間的差異？

Date date1; 
Date date2 ; 
int numberDays = ? 

Answer 1

的建議是使用JodaTime API的日期：

import java.util.logging.Logger; 

import org.joda.time.DateTime; 
import org.joda.time.Duration; 
import org.joda.time.Interval; 

public class DatesInterval { 
    private final static Logger log = Logger.getLogger(DatesInterval.class.getName()); 
    public static void main(String[] args) { 
     //creates a date 10 days ago in JodaTime 
     DateTime daysAgo10 = new DateTime().minusDays(10); 
     //today 
     DateTime today = new DateTime(); 

     //create an interval in Joda 
     Interval interval = new Interval(daysAgo10.getMillis(), today.getMillis()); 
     //than get the duration 
     Duration duration = interval.toDuration(); 

     //now you can get what you want. As you can imagine you can get days, millis, whateaver you need. 
     log.info("Difference in days: " + duration.getStandardDays()); 
    } 
}
