我們需要為netbeans中的本地電影院完成一個簡單的票務系統，我對兩個問題感到困惑。問題1是輸出的一部分，一旦你選擇了票據類型+數量，就需要輸出“你正在購買Y數量的X票”問題2是老年人的門票需要花費32.50美元，我似乎找不到允許使用小數字進行計算的解決方法。我調試了它似乎將數字更改為整數，然后無法正確計算。救命！package ticketingsystem;import java.io.*;public class ticketingsystem{
public static void main(String []args) throws Exception
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
String order,again;
int quantity,price1=0,price2=0, price3=0,loop1=0,quantity1,quantity2=0;
System.out.println(" ");
System.out.println("Welcome to the cinemas!");
System.out.println(" ");
System.out.println("MAIN MENU");
System.out.println(" ");
System.out.println("The cinema has the following options");
System.out.println(" ");
System.out.println("1 = Child (4-5 yrs)");
System.out.println("2 = Adult (18+ yrs)");
System.out.println("3 = Senior (60+ yrs)");
do{
System.out.println(" ");
System.out.print("Enter your option: ");
order=br.readLine();
if (order.equalsIgnoreCase("1")) {
price1=18;
} else if (order.equalsIgnoreCase("2")) {
price1=36;
}
else if (order.equalsIgnoreCase("3")) {
price1= (int) 32.5;
}
System.out.print("Enter the number of tickets: ");
quantity1= Integer.parseInt(br.readLine());
quantity2=quantity1+quantity2;
price2=price1*quantity2;
System.out.println("You are purchasing " int (order=br) " tickets at" (quantity1);
System.out.print("Do you wish to continue? (Y/N) : ");
again=br.readLine();
if (again.equalsIgnoreCase("y"))
loop1=loop1+1;
else loop1=loop1-100;
} while (loop1==1);
System.out.println(" ");
System.out.println("Total Price : "+price2);
}}
