java - 函数未返回正确的值，正在列表中查找值

Question

我有一个具有如下功能的类:

public void createFlight(String aname, String orig, String dest, String id) {
    Flight f = new Flight(aname, orig, dest, id);
    boolean found = false;
    boolean quit = false;
    for (int i = 0; i < flightList.size(); i++) {
        //Check origin exist
        if (airportList.get(i).getName().equals(orig))
            found = true;
        if (!found) {
            System.out.println("Origin " + orig + " does not exist.");
            quit = true;
        }
        found = false;
        //check destination exists
        if (airportList.get(i).getName().equals(dest))
            found = true;
        if (!found) {
            System.out.println("Destination " + dest + " does not exist.");
            quit = true;
        }
        //check if origin and destination are the same
        if (orig.equals(dest)) {
            System.out.println(id + "'s Origin and destination cannot be the same.");
            quit = true;
        }
    }
    if (!quit) {
        flightList.add(f);
        System.out.println("Added flight " + id);
    }
}

如果我运行:

    s.createFlight("USAIR", "ACE", "YVR", "778");//origin airport does not exist
    s.createFlight("BOS", "YHZ", "YUL", "123");

2号线应该正常运行，1号线的始发机场不存在。不过我得到了这个:

Added flight 778
Destination YUL does not exist.

这是错误的输出。我的预期输出会说第一个航类的出发地不存在。

不确定什么是什么，但我认为循环变量“i”应该从 0 运行到airPortList.size()。
