问题描述

下面的代码工作正常，除非 calendar.MONTH设置为1(2月)，并且我不知道为什么?谢谢.

The code below works fine except when calendar.MONTH set to 1 (Feb),and I do not know why ? Thanks.

    Calendar calendar = Calendar.getInstance();
    calendar.setLenient(false);    
    calendar.set(Calendar.YEAR, 2013);    
    calendar.set(Calendar.MONTH, 1); // Only when "Feb" failed with illegalArgumentException    

    int maxDays = calendar.getActualMaximum(Calendar.DAY_OF_MONTH); <= If Calendar.MONTH set to 1, this line will "java.lang.IllegalArgumentException"        

推荐答案

您正在getInstance中获取当前日期.然后，您将月份设置为2月.问题是今天是30日.二月有28天.那是非法的组合.将日期更改为有效日期，然后更改月份.

You're getting the current date in getInstance. Then you're setting the month to February. The problem is that today is the 30th. February has 28 days. That's an illegal combo. Change the day to a valid day, then change the month.
