java - 从 for 循环中的 if 退出 for 循环？

Question

我收到“有与此信息匹配的航类” “已记录乘客详细信息并完成预订”

但随后我也收到“没有飞往该目的地的航类”

for (int k = 0;k <=4; k++)
{
    if (destination.equalsIgnoreCase(flights[k].getDestination()))
    {
        k = 5;

        System.out.print("\nEnter desired day of departure: ");
        day = scan.nextLine();

        System.out.println("\f");

        if (day.equalsIgnoreCase(flights[k].getDay()))
        {

            if (flights[k].getBookedSeats() < 100)
            {

                passengers[0 + bookedSeats].setName(name);
                passengers[0 + bookedSeats].setAddress(address);
                passengers[0 + bookedSeats].setEmail(email);
                passengers[0 + bookedSeats].setOnFlight(k);
                flights[k].increaseBookedSeats();

                System.out.println("\nA flight is available matching this information");
                System.out.println("Passenger's details recorded and booking completed");

            }else{
                System.out.println("\nThere are no seats available on this flight");
            }
        }else
        {
            System.out.println("\nThere are no flights flying to this destination on this day");
        }
    }else if(!destination.equalsIgnoreCase(flights[k].getDestination()) && k==4)
    {
        System.out.println("\nThere are no flights flying to this destination");
    }

}

您可以在 if 条件内添加 break 语句以确保循环中断。
