不确定get(Calendar.DAY_OF_WEEK)返回的内容

Question

我的问题可以通过以下方案轻松创建:

 //create a gregorian calendar object that set the date and time as 4th June 2012 at 10:30PM
 Calendar calendar = new GregorianCalendar(2012, 6, 4, 22, 30);

 //when I print out these:
 System.out.println(calendar.get(Calendar.DAY_OF_WEEK));
 System.out.println(calendar.get(Calendar.MINUTE));
 System.out.println(calendar.get(Calendar.HOUR));
 System.out.println(calendar.get(Calendar.DATE));
 System.out.println(calendar.get(Calendar.MONTH));
 System.out.println(calendar.get(Calendar.YEAR));

 //output reads as:
 4
 30
 10
 4
 6
 2012

 //so does calendar.get(Calendar.DAY_OF_WEEK) == calendar.get(Calendar.DATE) ???

只是为了让每个人都清楚2012年6月4日是星期一,所以calendar.get(Calendar.DAY_OF_WEEK)不应该在一周的第一天返回0吗？

感谢您的所有帮助和疑虑,请同时验证您所指的来源.

java Calendar类中的月份是从0开始的.所以六月是第五个月.

你实际创建了一个代表7月4日的对象,恰好是星期三,也就是那个星期的第四天.
