Java用do while改写根据年份月份输出该月天数的程序,使程序能够判断10个年份月份的天数

使用do-while循环可以实现根据年份月份输出该月天数的程序，并且可以判断10个年份月份的天数。以下是示例代码：

import java.util.Scanner;

public class MonthDays {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int count = 1;
        
        do {
            System.out.println("请输入第" + count + "个年份：");
            int year = scanner.nextInt();
            System.out.println("请输入第" + count + "个月份：");
            int month = scanner.nextInt();
            
            int days = getMonthDays(year, month);
            System.out.println(year + "年" + month + "月的天数为：" + days);
            
            count++;
        } while (count <= 10);
        
        scanner.close();
    }
    
    public static int getMonthDays(int year, int month) {
        int days = 0;
        
        switch (month) {
            case 1:
            case 3:
            case 5:
            case 7:
            case 8:
            case 10:
            case 12:
                days = 31;
                break;
            case 4:
            case 6:
            case 9:
            case 11:
                days = 30;
                break;
            case 2:
                if (isLeapYear(year)) {
                    days = 29;
                } else {
                    days = 28;
                }
                break;
            default:
                System.out.println("输入的月份无效！");
        }
        
        return days;
    }
    
    public static boolean isLeapYear(int year) {
        return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0);
    }
}
