java - 如何计算男性和女性的理想体重范围

Question

当您输入高度时，我已经编码了男性和女性的理想体重。

import java.util.Scanner;
public class height
{
public static void main (String []args)
{
    int Feet, Inches, Totalinches, Maleweight, Femaleweight;
    Scanner scan = new Scanner (System.in);

    System.out.println ("Please enter your height in feet and inches...");

    System.out.println ("Feet: ");
    Feet = scan.nextInt();
    System.out.println ("Inches: ");
    Inches = scan.nextInt();

    Totalinches = Feet*12 + Inches; 
    Maleweight = 106 + (Totalinches - 60)*6;
    Femaleweight = 100 + (Totalinches - 60)*5;

    System.out.println ("The ideal weight for a " + Feet + " foot " + Inches +  " male is " + Maleweight + " pounds.");

    System.out.println ("A weight in the range  to  is okay.");

    System.out.println ("The ideal weight for a " + Feet + " foot " + Inches + " female is " + Femaleweight + " pounds.");

    System.out.println ("A weight in the range  and  is okay.");
}

}

其中显示“重量在范围内...” 我需要输入包含计算理想体重范围的公式的代码。此处有一张图表，其中列出了与高度相对应的所有理想体重范围:

如果您想使用该表中的值而不需要重复使用公式来计算它们，您可以使用一些映射来存储它们

    Map<Integer, Integer> minimumMaleWeight = new HashMap<>();
    minimumMaleWeight.put(54, 63);
    minimumMaleWeight.put(55, 68);
    minimumMaleWeight.put(56, 74);
    minimumMaleWeight.put(57, 79);      

    Map<Integer, Integer> maximumMaleWeight = new HashMap<>();
    maximumMaleWeight.put(54, 77);
    maximumMaleWeight.put(55, 84);
    maximumMaleWeight.put(56, 90);
    maximumMaleWeight.put(57, 97);

    System.out.println(minimumMaleWeight.get(Totalinches));
    System.out.println(maximumMaleWeight.get(Totalinches));

如果您想使用公式来计算它们，看起来向上舍入 5.4*Totalinches-228.7 可能会起作用( here is where I got the numbers ，您可以对最大重量执行相同的操作)
