Sorting arrays from lowest to highest numbers with ratios using methods in Java
问题
我正在编写一个程序，该程序接收配料的数量。程序如下：
import java.util.Scanner;
public class Restaurant {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int count = scan.nextInt();
}
}

int count = scan.nextInt();
}

将这个sortCalories函数更改为以下方式。还需要将价格数组作为第二个参数传递，就像这样：sortCalories(calories, price, ingredientName);：
public static void sortCalories(double[] calories, double[] price, String[] ingredientName) {
double temp;
String temp1;
for (int p = 0; p < calories.length; p++) {
for (int j = p + 1; j < calories.length; j++) {
if (calories[p] / price[p] > calories[j] / price[j]) {
temp = calories[p];
calories[p] = calories[j];
calories[j] = temp;
temp = price[p];
price[p] = price[j];
price[j] = temp;
temp1 = ingredientName[p];
ingredientName[p] = ingredientName[j];
ingredientName[j] = temp1;
}
}
}
}
英文:
Change this sortCalories function to the one below. Also you need to pass price array as second parameter like this sortCalories(calories,price, ingredientName);:
public static void sortCalories(double[] calories,double[] price, String[] ingredientName) {
double temp;
String temp1;
for (int p=0; p<calories.length; p++) {
for (int j=p+1; j<calories.length; j++) {
if(calories/price
>calories[j]/price[j]) {
temp = calories
;
calories
= calories[j];
calories[j] = temp;
temp = price
;
price
= price[j];
price[j] = temp;
temp1 = ingredientName
;
ingredientName
= ingredientName[j];
ingredientName[j] = temp1;
}
}
}
}
