根据文档,日历 set() 是:
According to doc, calendar set() is:
http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html#set%28int,%20int,%20int%29
set(int year, int month, int date)
Sets the values for the calendar fields YEAR, MONTH, and DAY_OF_MONTH.
代码:
Calendar c1 = GregorianCalendar.getInstance();
c1.set(2000, 1, 30); //January 30th 2000
Date sDate = c1.getTime();
System.out.println(sDate);
输出:
Wed Mar 01 19:32:21 JST 2000
为什么不是 1 月 30 日???
1 月是二月.2 月 30 日改为 3 月 1 日.您应该为月份设置 0.最好是使用 Calendar 中定义的常量:
1 for month is February. The 30th of February is changed to 1st of March. You should set 0 for month. The best is to use the constant defined in Calendar:
c1.set(2000, Calendar.JANUARY, 30);
