Run the following code, what do you expect to output?
/ / Hypothesis now is 11:34:03 Calendar Cal = Calendar.GetInstance (); caledar.Hour_of_day, 5); Cal.clear (Calendar.Hour_Of_Day); Cal.clear (Calendar.Calendar.second ); System.out.println ("h:" Cal.get (Calendar.Hour_Of_Day) ", S:" Cal.Get (Calendar.Second);
You must think of h: 0, s: 0
What? Isn't it? Where is H: 5, S: 3
neither!!!
Output H: 11, S: 0
Oh, is it incredible?
The original Calender's Clear (int) method is not clear,
For Hour, Hour_Of_DAY is returning the most original value.
Other may be clear.
In short, it is not an insurance method, or it is still replaced with a method such as Set (Hour, 0).
