Question

我需要用Java创建一个程序来计算一个有4个房间的房子的面积。我不确定如何开始这个，因为我是java的新手。我可以选择房间的尺寸，因此根本不需要用户输入。据我所知，我可以使用长度*宽度来获得房间的平方英尺，然后将所有四个房间添加到房屋面积中。我只是不确定如何设置这一切。

public class sqfoot {
    public static void main(String args[]){
        double length, width;
        room1
    }

}

到目前为止，这就是我所拥有的一切。有人可以帮帮我吗？

Answer 1

这是我提出的基本答案......我相信有很多简单的方法可以做到这一点。

public class sqfoot { public static void main（String [] args）{

    int House1_length1 = 14;
    int House1_width1 = 20;
    int House1_length2 = 10;
    int House1_width2 = 18;
    int House1_length3 = 10;
    int House1_width3 = 17;
    int House1_length4 = 17;
    int House1_width4 = 14;

    int House1_Area = ((House1_length1 * House1_width1) +
            (House1_length2 * House1_width2) +  
            (House1_length3 * House1_width3) + 
            (House1_length4 * House1_width4));

    System.out.println("House 1 square footage is " + ((House1_length1 * House1_width1) +
                        (House1_length2 * House1_width2) +  
                        (House1_length3 * House1_width3) + 
                        (House1_length4 * House1_width4)) + " Sq feet");

    int House2_length1 = 13;
    int House2_width1 = 21;
    int House2_length2 = 12;
    int House2_width2 = 17;
    int House2_length3 = 11;
    int House2_width3 = 15;
    int House2_length4 = 13;
    int House2_width4 = 14;

    int House2_Area = ((House2_length1 * House2_width1) +
            (House2_length2 * House2_width2) +  
            (House2_length3 * House2_width3) + 
            (House2_length4 * House2_width4));

    System.out.println("House 2 square footage is " + ((House2_length1 * House2_width1) +
            (House2_length2 * House2_width2) +  
            (House2_length3 * House2_width3) + 
            (House2_length4 * House2_width4)) + " Sq feet");

    System.out.println("House 1 is larger than house 2 by " + (House1_Area - House2_Area) + " Sq feet");







}

}

Answer 2

使用以下内容完成代码：

import java.util.Scanner;

public static void main(String[] args){

Scanner scan = new Scanner(System.in);

double len = 0;
double wid = 0; 

System.out.print("Enter the length in feet:(##.##) ");

   len = scan.nextDouble();

System.out.print("\nEnter the width in feet: (##.##) ");

   wid = scan.nextDouble();

System.out.print("\n"+"The area is "+wid*len+" square feet.");

}
