Java 使用printf（）时出现问题

这是到目前为止我的代码

import java.util.Scanner;
public class two {

    public static void main(String[] args) {
        System.out.println("--- Stage 1 Taxi Fare Calculator ---");

        Scanner user_input = new Scanner( System.in );

        System.out.print("Enter in pick up time:  ");
        System.out.flush();
        String startTime = user_input.next();

        System.out.print("Enter in pickup point:  ");
        System.out.flush();
        String pickUp = user_input.next();

        System.out.print("Enter in drop off point:  ");
        System.out.flush();
        String dropOff = user_input.next();

        System.out.print("Enter in trip distance in km:  ");
        System.out.flush();
        Double tripDist = user_input.nextDouble();
        user_input.nextLine();

        Double fareRate = 1.60;
        Double baseFare = tripDist * fareRate;
        Double totalFare = baseFare;

        String m1 = "The pickup point was: %15s%n";
        String m2 = "The drop off point was: %13s%n";
        String m3 = "The pickup time was: %11s%n";
        String m4 = "Estimated distance (km): %12f%n";
        String m5 = "Fare Charged: $%11.2f%n";
        String m6 = "Base fare: $%15.2f%n";
        String m7 = "Total fare: $%14.2f%n";
        String m8 = "Plus surcharges: $%14.2f%n";
        System.out.println(" --- Taxi fare details --- ");
        System.out.printf(m1, pickUp); 
        System.out.printf(m2, dropOff);
        System.out.printf(m3, startTime);
        System.out.printf(m4, tripDist);
        System.out.printf(m5, fareRate);
        System.out.printf(m6, baseFare);
        System.out.printf(m7, totalFare);
    }


}

EDIT2（最终版）：我在我的代码中添加了更多内容，现在得到了你们在上面看到的内容，现在我所需要做的就是添加附加费，所以当某个时间是一定的成本，而且该区域也有附加费，无论如何，不要在那里寻求帮助，只是让你们知道你们已经帮了很多忙，我感谢你们。顺便说一句，如果我没有像现在这样多地编辑这些内容，我深表歉意。

如果您在读取变量的同一行上声明变量，那么代码可能会更短，如果您没有

println（）

，那么您应该

flush（）

，也就是说

System.out.print("Enter in pick up time:  ");
System.out.flush();
String startTime = user_input.next();

System.out.print("Enter in pickup point:  ");
System.out.flush();
String pickUp = user_input.next();

System.out.print("Enter in drop off point:  ");
System.out.flush();
String dropOff = user_input.next();

System.out.print("Enter in trip distance in km:  ");
System.out.flush();
Double tripDist = user_input.nextDouble();
user_input.nextLine();

然后，您需要在格式

字符串
（s）中包含输出类型

接下来，当调用
printf（）
时，应该传递参数，而不是串联参数-

System.out.printf(m1, pickUp);
System.out.printf(m2, dropOff);
System.out.printf(m3, startTime);
System.out.printf(m4, tripDist);
System.out.printf(m5, fareRate);
System.out.printf(m6, baseFare);
System.out.printf(m7, totalFare);

然后我想它会像你期望的那样工作。
只是一个注释，叫做
user\u input.nextLine（）nextDouble（）
之后加上code>，否则你会拉一个空白输入。啊，好的，谢谢你，流氓：）你应该加一个
双倍票价=0.35或提示用户输入费率（为什么不使用原语类型
double
？），然后
double fare=行程距离*费率。啊，你太棒了，非常感谢。这里的每个人都帮了大忙：D
System.out.printf(m1, pickUp);
System.out.printf(m2, dropOff);
System.out.printf(m3, startTime);
System.out.printf(m4, tripDist);
System.out.printf(m5, fareRate);
System.out.printf(m6, baseFare);
System.out.printf(m7, totalFare);
