The setting problem of JAVA calendar

Calendar has two modes to interpret calendar fields, namely, loose and.

Not tolerant. When the calendar is spacious.

Mode, it can accept a larger range of values than the range of calendar fields it generates. When Calendar recalculates the calendar field values, so that

When get () returns these values, all calendar fields are standardized. For example, in the relaxed mode

GregorianCalendar will month = =

January and a day in January == 32 is interpreted as February 1.

Analysis program:

After the implementation of cal.set (July 3, 20031), the date indicated by cal is August 3, 20031;

Executing cal.set(Calendar. Month, 8), it should be September 3, 20031. However, there is no September 3 1, so the month will be recursively changed to June 2003 10.
