Question

我根据摄氏温度和海拔高度编写代码来确定水的状态，如何在最后完成，如果海拔高于300，则需要1摄氏度以下的摄氏温度。煮沸的水和结果可以根据输入确定？

import java.util.Scanner;

public class WaterState
{       
    public static void main(String[] args)
    {
        boolean run = true;
        while(run)
        {
            Scanner scan = new Scanner(System.in);

            System.out.println("What is the temperature in degrees Celsius?");
            double temp = scan.nextDouble();
            System.out.println("What is the height above Sea level? in exact meters");
            double altitude = scan.nextDouble(); 

            int freezingPoint = 0;
            double alternateAltitude = temp - (altitude * 0.001);
            double boilingPoint = 100;
            int baseAltitude = 300;

            if ((temp <= freezingPoint) && (altitude <= baseAltitude))
            {
                System.out.println("Water is frozen");
            }
            else if ((temp > freezingPoint) && (altitude <= baseAltitude))
            {
                System.out.println("Water is liquid");
            }
            else if ((temp >= boilingPoint) && (altitude <= baseAltitude))
            {
                System.out.println("Water is gaseus");
            }

            else if ((altitudeChange > )
            {  

                System.out.println("Water is boiling, but at a lower temperature because of the altitude");

        }
    }
}
}

以下是您的问题的相关内容：

        else if ((altitudeChange > ){ 
            System.out.println("Water is boiling, but at a lower temperature because of the altitude");
        }

根据你的意见：

如果海拔高于300，则需要1摄氏度水煮沸，结果可以根据输入

这是你想要的：

if(altitude >=baseAltitude  && temp>(boilingPoint -(altitude/baseAltitude *1)) ){//1.altitude is more than 300,2.temp is higher than the new degree celsius to boil 
 System.out.println("Water is boiling, but at a lower temperature because of the altitude");
}

我正在编写代码以使用if语句确定水的状态
