java程序关于日历代码的解读
类CalendarPrinter有两个主要的方法printCal()和printOut()，printCal()打印你输入年份的每一个月份，printOut()打印每一个月的每一天，在printCal()方法先创建一个格里高利历法的对象，并把你输入的年份设置为该历法的年份，然后for循环打印12个月份，然后再把每个月分别设置为你输入那年的每个月，接着调用printOut()方法打印每一天，在printOut()方法中，先获得月份，然后把日期设置为该月的第一天，接着在获取这月的第一天是一周中的周几weekday，然后打印出第一行“Sun MOn Tue Wed Thu Fri Sat”，接着就进入for循环，这个for循环就是打印每个月第一天开始前的空格，接着就进入do……while循环，获得天day，如果day10，打印day的时候day前面的空格大一些，否则day前面的空格就小一些，为了排版好看，然后判断是否是周六，如果是周六就换行，然后把day+1，重新获得新的day在一周中是周几。循环一直下去，该月的天从1一直加到30或31，再加的话月份就该+1，所以do……while循环结束的条件就是进入到下一个月。最后判断该月的最后一天是不是该月的周日，如果不是就换行
