Java日历设置不正确 [英] Java Calendar Setting Incorrectly

问题描述

我对Java的日历有些麻烦。我从一个txt文件解析一些数据，需要创建一个日期。完成以下代码后：

I'm having some trouble with Java's Calendar. I'm parsing some data from a txt file, and need to create a date. After completion of the following code:

tmpYear = Double.parseDouble(row[yearIndex]);
tmpMonth = Double.parseDouble(row[monthIndex]);
tmpDay = Double.parseDouble(row[dayIndex]);
if(timeIndex != -1)
    tmpTime = Double.parseDouble(row[timeIndex]);
if(secondsIndex != -1)
    tmpSeconds = Double.parseDouble(row[secondsIndex]);

我可以调试并看到变量如下：
tmpYear == 2010 < br>
tmpMonth == 12

tmpDay == 30

tmpTime == 15（这是一天中的小时）

tmpSeconds = = 0

I can debug and see that the variables are as follows: tmpYear == 2010
tmpMonth == 12
tmpDay == 30
tmpTime == 15 (This is the hour of the day)
tmpSeconds == 0

但是当运行以下代码时：

But when running the following code:

cal.set((int)tmpYear,(int)tmpMonth,(int)tmpDay,(int)tmpTime,
            (int)((tmpTime - (int)tmpTime)*100),(int)tmpSeconds);
System.out.println(cal.getTime().toString());

我得到这个输出：

Sun Jan 30 15： 00:00 CST 2011

I'm getting this for an output:
Sun Jan 30 15:00:00 CST 2011

有人可以解释这可能是什么原因吗？先谢谢大家的帮助！

Can someone explain what a possible reason for this would be? Thank you all in advance for the help!

推荐答案

月份的索引为0-11而不是1-12。

0 =一月

1 =二月

...

11 =十二月

使用 tmpMonth = value -1 。

months are indexed 0-11 instead of 1-12.
0 = January
1 = February
...
11 = December
Use tmpMonth = value -1 instead.
