Deep understanding of the set and get methods of calendar

/**
 * Calendar provides a set method
 * You can set a time component with a given value
 * Time component using a number of constants provided by Calendar

public class Calendardemo {public
	static void Main (String args[]) {
		Calendar calendar=calendar.getinstance (); c2/>/*
		 * 2008-08-08 20:22:35 * If the value of the
		 set time unit will affect the value that is not set,
		 * Then the value will also correspond to the change is like,
		 * We set the date of the month, then the corresponding weeks will follow the change.
		 * *
		Calendar.set (calendar.year, 2014);
		Calendar.set (calendar.month,10);
		 * * * month is starting from 0, 0 for January
		 * day_of_month  usually said "number"
		 * day_of_year   usually said the first days
		 * Day_of_weer   Usually say the week
		 //		Calendar.set (calendar.am_pm);		Calendar.set (Calendar.hour, 8);
		Calendar.set (calendar.day_of_month,25);
		Calendar.set (Calendar.hour_of_day, one);
		*
		 * * The calendar will automatically carry * when the set unit value exceeds the maximum allowable value of the unit * The
		 hour will be put to the Sky
		 * Set week will also affect the
		 date 
		 *
		* * * Calendar.set (Calendar.minute, one);
		Calendar.set (Calendar.second, one);
		
		
		1 indicates Sunday, 2 indicates Monday
