因此,此代码应该每天添加总计并显示总销售额
但是由于某种原因,答案始终是天数的平方
我认为这是由于其他Java文件打开导致的,因此我删除了它们,但没有帮助
package com.test;
import javax.swing.*;
public class test_3
{
public static void main(String[] args)
{
int days; //number of days
double sales; // sales per day
double TotalSales = 0.0; // Total sales
String input = JOptionPane.showInputDialog("For how many days is the sales ?");
days = Integer.parseInt(input); //converting days into number
for(int count = 1; count <= days; count++)
{
JOptionPane.showInputDialog("Enter sales amount of day " + count);
sales = Double.parseDouble(input);
TotalSales += sales;
}
JOptionPane.showMessageDialog(null,"Total sales is "+ TotalSales);
}
}
我该怎么办?
答案 0 :(得分:0)
此行:
JOptionPane.showInputDialog("Enter sales amount of day " + count);
应为:
input = JOptionPane.showInputDialog("Enter sales amount of day " + count);
否则,input
仍然是您从第一个提示(多少天)中获得的值,因此您要将该金额与该总次数相加,从而得出平方。
