Java以十进制年数表示的时间段 [英] Java Time period in decimal number of years

问题描述

如果我使用以下方法计算 java.time 中2 LocalDate 之间的差异：

If I calculate the difference between 2 LocalDate's in java.time using:

Period p = Period.between(testDate, today);

然后我得到一个年，月，天数的输出：

Then I get an output with the number of years, months, days like:

Days = 9
Months = 6
Years = 18

有没有人知道一种干净的方式来表示它作为十进制类型值（即，上面将是 18.5 ... ）

Does anyone know a clean way to represent that as a decimal type value (ie, above would be something around 18.5...)?

推荐答案

我会避免使用Period，而只是计算天数的差异：

I would avoid using Period, and instead just calculate the difference in days:

float years = testDate1.until(today, ChronoUnit.DAYS) / 365.2425f;
