将两个长变量相除然后减去得到零

Question

亲爱的，

我的 Java 代码中有一个小问题。代码应该划分两个长数字（这很好用）。当从结果中减去时它给出零，而它应该给出另一个结果！

该代码是关于在给定的分钟数内获取年数和天数。

import java.util.Scanner;

public class TestMinsToYearsDays {

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  MinsToYearsDays minsToYearsDays = new MinsToYearsDays();
  
  Scanner sc = new Scanner(System.in);  
  System.out.print("Enter the number of Minutes: ");
  minsToYearsDays.miniute = sc.nextLong();
  
  long years;
  years = minsToYearsDays.miniute / 525600L;
  
  long remaining;
  remaining = ((  years-(minsToYearsDays.miniute / 525600L) ) * 365L);
  
  System.out.println("\n Minutes are approximatly " + years + " years and " + remaining + " days " + minsToYearsDays.miniute);
 }

}

Answer 1

years = minsToYearsDays.miniute / 525600L;

表示

years-(minsToYearsDays.miniute / 525600L) == 0

因此

remaining = ((years-(minsToYearsDays.miniute / 525600L)) * 365L);

为 0。

你的公式错了。如果你想计算剩余的分钟数（减去整年之后），它应该是：

remainingMinutes = minsToYearsDays.miniute - years * 525600L;

如果要计算剩余天数，应该是：

remainingDays = (minsToYearsDays.miniute - years * 525600L) / 1440;

Divide two long vars then subtract gives zero
