操作方法
代码如下：
代码1 package com.huangtao.sxt; import java.util.Scanner; public class Test1 { public static void main(String args[]){ //创建日期对象 System.out.println("输入年份"); int y=getScanner(); System.out.println("输入月份"); int m=getScanner(); System.out.println("输入日期"); int d=getScanner(); YearMonthDay day=new YearMonthDay(y,m,d); System.out.println("输入日期是："+day.getYear()+"年"+day.getMonth()+"月"+day.getDay()+"日"); day.isExits(); System.out.println("第"+day.totleDays()+"天"); } /* * 获取输入 */ public static int getScanner(){ Scanner sc= new Scanner(System.in); return sc.nextInt(); } }
演示
package com.huangtao.sxt; public class YearMonthDay { private int year; private int month; private int day; //使用一个静态数组变量 public static int[] months={31,28,31,30,31,30,31,31,30,31,30,31}; public int getYear() { return year; } public void setYear(int year) { this.year = year; } public int getMonth() { return month; } public void setMonth(int month) { this.month = month; } public int getDay() { return day; } public void setDay(int day) { this.day = day; } public YearMonthDay(){ } public YearMonthDay(int year, int month, int day) { super(); this.year = year; this.month = month; this.day = day; } /* * 判断是否是闰年 * 4年一闰，百年不闰，400年又闰 */ private void isRunYear(){ if((this.year%4==0&&this.year%100!=0)||this.year%400==0){ //闰年 months[1]=29; }else{ //平年 months[1]=28; } } /* * 天数计算 */ public int totleDays(){ isRunYear(); int totle = 0; for(int i=0;i<month-1;i++){ totle = totle+months[i]; } totle =totle+this.day; return totle; } /* * 判断用户输入是否存在 */ public void isExits(){ if(month<0||month>12){ System.out.println("月份错误"); System.exit(0); } if(day<0||day>31){ System.out.println("日期错误"); System.exit(0); } } }
