构造函数类预订中的预订不能应用于给定类型

Question

构造函数类预订中的预订不能应用于给定类型。任何修复章节？

import java.util.ArrayList;
/**
  * Imports the Array List required for the application to use methods such as add, remove, size ect.
*/
public class Trip {

        private ArrayList<Bookings> Booking;
        public String Date;
        public String Trip;
        public String Code;
        public double price;
        public int booking_id;

        {
             Booking = new ArrayList<Bookings>();
             booking_id = 0;
             tripID = ltripID;
             tripDestination = ltripDestination;

             booking_id++;

             newbooking = new Bookings(Code, noAdults, noChildren, cForename, cSurename, cNumber, booking_id);

Answer 1

说这个：

new Bookings(Code, noAdults, noChildren, cForename, cSurename, cNumber, booking_id);

您希望Bookings类中存在以下构造函数签名：

Bookings(String, int, int, String, String, String, int)

找出哪个参数索引与构造函数声明不匹配。
