java - 如何将事件从一个链表移动到另一个链表

Question

我正在为我的模拟课程做一个围绕机场模拟的项目。目标是事件到达不同的车站或终点站，我需要公共汽车将事件带到正确的目的地。我可以创建事件并将它们放置在正确的终端中。我遇到问题的地方是将事件从一个链接列表移动到另一个链接列表。

例如，如果一个事件出现在 A 站，我需要它上公共汽车，然后在终点站下车。

while(passengers < 200){

     /*
     * This first section is where I create my events and place 
     * them in their appropriate places.
     */


    Random ran = new Random();
    int x = ran.nextInt(4) + 1;

    for(int i = 1; i <= x; i++){

    //passengers arrival time
        double U = random.nextFloat();
        double nextArrival =  -(Math.log(U))/lambda;    
    //double nextDeparture = -(Math.log(U))/mu;

    //determines place of origin and destination
        Random r = new Random();
        int randnum = r.nextInt(places.length);
        int randnum1 = r.nextInt(places.length - 1);
        String o = places[randnum];
        String d;
        if(o.equalsIgnoreCase("Terminal") ) d = places[randnum1];
        else d = places[3];

    //creates new event
        Event a = new Event(nextArrival, o, d);

    //place event at origin
        if(o.equalsIgnoreCase("StationA")){
            StationA.insert(a);
            StationA.curSize++;
        }
        else if(o.equalsIgnoreCase("StationB")){
            StationB.insert(a);
            StationB.curSize++;
        }
        else if(o.equalsIgnoreCase("StationC")){
            StationC.insert(a);
            StationC.curSize++;
        }
        else {
            Terminal.insert(a);
            Terminal.curSize++;
        }


        passengers++;

    }

    /*
     * Now bus has to go to all stations and terminal
     */

    //BUS GOES TO STATION A
    //people have to get off bus first

    if(Bus.isEmpty()) break;
    else {
        while(StationA.curSize != StationA.limit){
            boolean w = Bus.findEventTF("StationA");
            if(w = true){
                //find an event that needs to get off bus
                Event a = Bus.findEvent("StationA");
                //place event stationa completed list
                CompletedA.addLast(a);
                //increase current size of stationa completed list
                CompletedA.curSize++;
                //remove event from bus
                Bus.delete(a);
                //decrease current size of bus list
                Bus.curSize--;
            }
        }
    }

    //people have to get on bus from station a

    if(StationA.isEmpty()) break;
    else {
        while(Bus.curSize != Bus.limit){
            boolean w = Bus.findEventTF("Terminal");
            if(w = true){
                //find an event that needs to get on bus
                Event a = StationA.findEvent("Terminal");
                //place event on bus
                Bus.addLast(a);
                //increase current size of bus
                Bus.curSize++;
                //remove event from StationA
                StationA.delete(a);
                //decrease current size of stationa
                StationA.curSize--;
            }
        }
    }

    /*
     * 
     * Right now im trying to work on Station A and Terminal
     * before i add Station B & C
     * 
     */

    //BUS GOES TO TERMINAL
    //people have to get off bus first

    if(Bus.isEmpty()) break;
    else {
        while(Terminal.curSize != Terminal.limit){
            boolean w = Bus.findEventTF("Terminal");
            if(w = true){
                //find an event that needs to get off bus
                Event a = Bus.findEvent("Terminal");
                //place event terminal completed list
                CompletedT.addLast(a);
                //increase current size of terminal completed list
                CompletedT.curSize++;
                //remove event from bus
                Bus.delete(a);
                //decrease current size of bus list
                Bus.curSize--;
            }
        }
    }

    //people have to get on bus from terminal

    if(Terminal.isEmpty()) break;
    else {
        while(Bus.curSize != Bus.limit){
            //boolean w = Bus.findEventTFTerm('S');
            if(Bus.findEventTFTerm('S') = true){
                //find an event that needs to get on bus
                Event a = StationA.findEventTerm('S');
                //place event on bus
                Bus.addLast(a);
                //increase current size of bus
                Bus.curSize++;
                //remove event from StationA
                Terminal.delete(a);
                //decrease current size of terminal
                Terminal.curSize--;
            }
        }
    }

}

如果我一个人做第一部分，它会起作用，当我尝试移动它时，它不会。任何帮助将不胜感激。如果您希望我从我的链表类中添加代码，请告诉我。谢谢。
