org.joda.time.DateTime 时间操作类

1、当前时间加上3天
 

        DateTime dateTime = new DateTime();
		dateTime = dateTime.plusDays(3);
		System.out.println(dateTime.toString("yyyy-MM-dd"));

2、比较两个日期的天数差
 

public static void main(String[] args) {
		DateTime dateTime = new DateTime();
		DateTime dateTime2 = dateTime.plusDays(5);
		
		System.out.println(dateTime2.toString("yyyy-MM-dd"));
		
		int days = Days.daysBetween(dateTime, dateTime2).getDays();
		System.out.println(days);

	}
