java学习之路——小例子（实现输入年份，输出该年份的具体天数信息）
实现输入年份，输出该年份的具体天数信息。练手的代码：
package com.lcq.ThreadTest;
import java.util.Scanner;
public class Test2 {
/**
* 功能：打印出输入年份的每一天的信息
* @version 1.0
* @author lcq
*/
//countDays(int month, int year)函数用来计算这一年中每个月的天数
int countDays(int month, int year){
int count = -1;
switch(month){
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
count = 31;
break;
case 4:
case 6:
case 9:
case 11:
count = 30;
break;
case 2:
if(year % 4 == 0)
count = 29;
else
count = 28;
if((year % 100 ==0) & (year % 400 != 0))
count = 28;
}
return count;
}
public static void main(String[] args) {
//初始化该类
Test2 t = new Test2();
System.out.println("请输入year ：");
Scanner q=new Scanner(System.in);
//y 变量接受输入的year
int y=q.nextInt();
//遍历12个月份分别输出每一天
for (int i = 1; i <= 12; i++) {
//n变量用于标记该月的天数
int n = 0;
n = t.countDays(i,y);
for (int j = 1; j <= n; j++) {
System.out.println(i + "月" + j +"日");
}
}
}
}
