无法使用 joda time 获得两个日期之间的正确差异

Question

我正在尝试使用 joda time 获取两个日期之间的差异，但不知何故我无法获得确切的差异。

        LocalDate endofCentury = new LocalDate(2014, 01, 01);

        LocalDate now = LocalDate.now(); //2017-04-11

        Period diff = new Period(endofCentury, now); 

        System.out.printf("Difference is %d years, %d months and %d days old", 
                            diff.getYears(), diff.getMonths(), diff.getDays());

差异应该是 3 年 3 个月 10 天 但我得到 3 年 3 个月零 3 天 .

不确定我缺少什么，请帮助我。

谢谢

Answer 1

使用带 3 个参数的构造函数：

Period diff = new Period(endofCentury, now, PeriodType.yearMonthDay());

带 2 个参数的构造函数 (from,to) 包括周数。

所以你的代码的修改输出：

Period diff = new Period(endofCentury, now);
System.out.printf("Difference is %d years, %d months and %d weeks and %d days old",
                diff.getYears(), diff.getMonths(),diff.getWeeks(), diff.getDays());

给出输出：

Difference is 3 years, 3 months and 1 weeks and 3 days old

但具有指定的持续时间字段（第 3 个参数）：

Period diff = new Period(endofCentury, now, PeriodType.yearMonthDay());
System.out.printf("Difference is %d years, %d months and %d weeks and %d days old",
            diff.getYears(), diff.getMonths(),diff.getWeeks(), diff.getDays());

你得到：

Difference is 3 years, 3 months and 0 weeks and 10 days old
