Java轉換天數

Question

我需要使用模操作數將輸入的天數轉換為其等效的年/秒，月/秒，周/秒和天數。 我們昨天才開始討論，所以我還是有些生銹，但這是我制作的程序：

import java.util.Scanner;

public class DaysConvert {
   public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    int noOfDays, year, month, week, days;

    System.out.print("Enter Number of Days: ");
    noOfDays = input.nextInt();

    year = noOfDays/365;
    month = year%365;
    week = month%30;
    days = week%7;

    System.out.println("Year: " + year);
    System.out.println("Month: " + month);
    System.out.println("Week: " + week);
    System.out.println("Day: " + days);
}
}

我的算法有問題嗎？

Answer 1

如果您只打算在一年中的365 days中固定一個月中的30 days而沒有then年，那么您可以迭代到for循環中的天數，並從用戶輸入的內容中檢查每一天的模數。

樣品：

    for(int i = 1; i < noOfDays+1; i++)
    {
        if((i %30) == 0)
            month++;
        if((i%7) == 0)
            week++;
        if((i%365) == 0)
            ++year;
        if((i%1) == 0)
            days++;

    }

    System.out.println("Year: " + year);
    System.out.println("Month: " + month);
    System.out.println("Week: " + week);
    System.out.println("Days: " + days);

結果：

Enter Number of Days: 330
Year: 0
Month: 11
Week: 47
Days: 330

Answer 2

這將正常工作：

year = (double) (noOfDays/365);

    month=noOfDays/30.41;

   week=noOfDays/7;

我希望這有幫助。

像這樣做：

public class DaysConvert
{
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int noOfDays, year, month, week, days;

        System.out.print("Enter Number of Days: ");
        noOfDays = input.nextInt();

        year = noOfDays/365;
        noOfDays=noOfDays%365;

        month = noOfDays/30;
        noOfDays=noOfDays%30;

        week = noOfDays/7;
        noOfDays=noOfDays%7;


        System.out.println("Year: " + year);
        System.out.println("Month: " + month);
        System.out.println("Week: " + week);
        System.out.println("Day: " + noOfDays);
    }
}
