布兰登,没有哨兵循环。在我看来,这就是你想要的程序,
import java.util.*;
public class Stack3{
public static void main(String []args){
int count=0;
int days;
double DailyFee=0, NontaxTotal, CarType, Total,FullTotal=0;
Scanner in=new Scanner(System.in);
System.out.println("If there are any customer press 1 else press 0");
int cus=in.nextInt();
// this is sentinel loop
while(cus!=0){
count++;
System.out.print("What vehical would you like to rent?\n");
System.out.println("Enter 1 for an economy car\n");
System.out.println("Enter 2 for a sedan car\n");
System.out.println("Enter 3 for an SUV");
CarType = in.nextInt();
if (CarType == 1)
DailyFee=31.76;
else if(CarType == 2)
DailyFee=40.32;
else if(CarType == 3)
DailyFee=43.50;
System.out.print("Please enter the number of days rented. (Example; 3) : ");
days = in.nextInt();
double x=days;
NontaxTotal = (DailyFee * x);
Total = (NontaxTotal * 1.06);
FullTotal+=Total;
//included 2 decimals only
System.out.printf("The total amount due is $ %.2f \n",Total);
System.out.println("If there are any customer press 1 else press 0");
cus=in.nextInt();
}
System.out.println("Count of customers :- "+count);
System.out.printf("Total of the Day :- %.2f",FullTotal);
}
}
