为什么Java日历报告的日期不正确？ [英] Why is Java Calendar reporting the incorrect date?

问题描述

任何人都可以告诉我为什么当它是今天第22天（英国）时在控制台中显示'5'？！

Could anyone let me know why the following is displaying '5' in the console when it is the 22nd today (UK)?!

System.out.println(Calendar.DAY_OF_MONTH);

提前感谢！

推荐答案

Calendar.DAY_OF_MONTH 只是用于各种操作的常数（并且恰好其值为 5 ），您应该使用：

Calendar.DAY_OF_MONTH is just a constant used for various operations (and happens to be its value is 5), you should be using:

Calender.getInstance().get(Calendar.DAY_OF_MONTH);
