如何在Java中获得上个月/一年? [英] How to get last month/year in java?

问题描述

如何用Java找出最后一个月及其年份?

How do I find out the last month and its year in Java?

例如如果今天是2012年10月10日，则结果应为Month = 9和Year = 2012.如果今天是2013年1月10日，则结果应为Month = 12和Year = 2012.

e.g. If today is Oct. 10 2012, the result should be Month = 9 and Year = 2012. If today is Jan. 10 2013, the result should be Month = 12 and Year = 2012.

推荐答案

您的解决方案是

Your solution is here but instead of addition you need to use subtraction

c.add(Calendar.MONTH, -1);

然后，您可以调用

Then you can call getter on the Calendar to acquire proper fields

int month = c.get(Calendar.MONTH) + 1; // beware of month indexing from zero
int year  = c.get(Calendar.YEAR);
