Java 计算汽车油耗程序：轻松分析每升汽油行驶里程

import java.util.Scanner;

public class FuelConsumption { public static void main(String[] args) { Scanner input = new Scanner(System.in); double totalMiles = 0; // 总行驶里程 double totalFuel = 0; // 总加油量 double totalFuelEfficiency = 0; // 总油耗

    while (true) {
        System.out.print('请输入本次行驶英里数（输入-1结束）：');
        double miles = input.nextDouble();
        if (miles == -1) {
            break; // 输入-1结束循环
        }
        System.out.print('请输入本次加油量（单位：升）：');
        double fuel = input.nextDouble();

        double fuelEfficiency = miles / fuel; // 计算本次油耗
        System.out.printf('本次行驶每升汽油可供%.2f公里。\n', fuelEfficiency);

        totalMiles += miles; // 累加总行驶里程
        totalFuel += fuel; // 累加总加油量
        totalFuelEfficiency += fuelEfficiency; // 累加总油耗
    }

    double averageFuelEfficiency = totalMiles / totalFuel; // 计算平均油耗
    System.out.printf('所有行驶中，每升汽油可供%.2f公里。\n', averageFuelEfficiency);
    System.out.printf('总行驶里程：%.2f英里，总加油量：%.2f升，总油耗：%.2f。\n',
            totalMiles, totalFuel, totalFuelEfficiency);
}
