[问答题]

(驾驶费用）编写一个程序，提示用户输人驾驶的距离、以每加仑多少英里的汽车燃油性能，以及每加仑的价格，然后显示旅程的费用。下面是一个运行示例：

Raphus_Cucullatus

package com.jinling.day01;
import java.util.Scanner;

public class NKTest {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter the driving distance: ");
        double distance = sc.nextDouble();
        System.out.print("Enter miles per gallon: ");
        double milesPerGallon = sc.nextDouble();
        System.out.print("Enter price per gallon: ");
        double pricePerGallon = sc.nextDouble();
        sc.close();
//        使用该方法保留两位小数String.format(format,ags)
        System.out.print("The cost of driving is $" + String.format("%.2f", distance / milesPerGallon * pricePerGallon));
    }
}
