(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:
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)); } }
