java日历代码报告 java实现简单日历代码

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

* @Title:日期选择控件

* @Description:在原有基础上修改了以下内容：

* 1. 将容器由Frame改为了Dialog，以便在基于对话框的程序中也能够使用

* 2. 将最小日期由1980改为了1950，考虑到目前球员的出生日期可能早于1980年

* 3. 将初始显示格式设置为 yyyy年MM月dd日 格式，原有的小时去掉了，不适合于出生日期字段

用JAVA做日历，要求源代码

import java.util.Scanner; public class Wan{ public static void main(String[] args){ Scanner name = new Scanner(System.in); System.out.print("请输入要查询的年份:"); int year = name.nextInt(); System.out.print("请输入该年的月份"); int month = name.nextInt(); } //累加 该年至输入的月份 天数 //比如 输入2009年的 3月分 // 那就累加 2009年的1月至 3月1号的总天数 public void sumDay(int year,int month){ int day = 0; int sumDay = 0; for(int i = 1;i=month;i++){ switch(i){ case 1: case 3: case 5: case 7: case 8: case 10: case 12: day = 31; break; case 2: if(year % 4 == 0 || year % 400 == 0 year %100!=0){ day = 29; }else{ day = 28; } break; default: day = 30; } //最后一个月份不要累加 因为我们只是要算到该月的一号就可以了 if(i month){ sumDay += day; } } //累加 2000年到该年的一月一号天数 for(int i = 2000;iyear;i++){ if( i % 4 == 0 || i %400== 0 i % 100 != 0){ sumDay += 366; }else{ sumDay += 365; } } //求该月一号为星期几 int week = sumDay % 7 +1; if(week == 7){ week = 0; } } public void fomatDate(int week,int day){ int g = 0; for(int i = 0;iweek;i++){ System.out.print("\t"); } for(int i = 1;i=day;i++){ System.out.print(i+"\t"); g = week + i; if(g % 7 == 0){ System.out.println(); } } } } 给点分哈 写得好累
