使用Java做一个数据结构火车管理系统

好的，下面是一个简单的数据结构火车管理系统的Java代码示例：

首先，我们需要定义一个火车类，包括车号、车型、座位等级、车站等信息：

public class Train {
    private String trainNumber;
    private String trainType;
    private String seatLevel;
    private String startStation;
    private String endStation;
    private int seatCount;

    public Train(String trainNumber, String trainType, String seatLevel, String startStation, String endStation, int seatCount) {
        this.trainNumber = trainNumber;
        this.trainType = trainType;
        this.seatLevel = seatLevel;
        this.startStation = startStation;
        this.endStation = endStation;
        this.seatCount = seatCount;
    }

    public String getTrainNumber() {
        return trainNumber;
    }

    public String getTrainType() {
        return trainType;
    }

    public String getSeatLevel() {
        return seatLevel;
    }

    public String getStartStation() {
        return startStation;
    }

    public String getEndStation() {
        return endStation;
    }

    public int getSeatCount() {
        return seatCount;
    }
}

然后，我们需要定义一个车站类，包括车站名称、到站时间、发车时间等信息：

public class Station {
    private String stationName;
    private String arriveTime;
    private String departTime;

    public Station(String stationName, String arriveTime, String departTime) {
        this.stationName = stationName;
        this.arriveTime = arriveTime;
        this.departTime = departTime;
    }

    public String getStationName() {
        return stationName;
    }

    public String getArriveTime() {
        return arriveTime;
    }

    public String getDepartTime() {
        return departTime;
    }
}

接下来，我们需要定义一个火车管理系统类，实现添加、查询、修改和删除火车信息等功能：

import java.util.ArrayList;
import java.util.List;

public class TrainManagementSystem {
    private List<Train> trainList;
    private List<Station> stationList;

    public TrainManagementSystem() {
        trainList = new ArrayList<>();
        stationList = new ArrayList<>();
    }

    public void addTrain(Train train) {
        trainList.add(train);
    }

    public void removeTrain(String trainNumber) {
        for (int i = 0; i < trainList.size(); i++) {
            if (trainList.get(i).getTrainNumber().equals(trainNumber)) {
                trainList.remove(i);
                break;
            }
        }
    }

    public Train getTrain(String trainNumber) {
        for (Train train : trainList) {
            if (train.getTrainNumber().equals(trainNumber)) {
                return train;
            }
        }
        return null;
    }

    public void updateTrain(String trainNumber, Train train) {
        for (int i = 0; i < trainList.size(); i++) {
            if (trainList.get(i).getTrainNumber().equals(trainNumber)) {
                trainList.set(i, train);
                break;
            }
        }
    }

    public void addStation(Station station) {
        stationList.add(station);
    }

    public void removeStation(String stationName) {
        for (int i = 0; i < stationList.size(); i++) {
            if (stationList.get(i).getStationName().equals(stationName)) {
                stationList.remove(i);
                break;
            }
        }
    }

    public Station getStation(String stationName) {
        for (Station station : stationList) {
            if (station.getStationName().equals(stationName)) {
                return station;
            }
        }
        return null;
    }

    public void updateStation(String stationName, Station station) {
        for (int i = 0; i < stationList.size(); i++) {
            if (stationList.get(i).getStationName().equals(stationName)) {
                stationList.set(i, station);
                break;
            }
        }
    }
}

最后，我们可以在主函数中测试这个火车管理系统：

public static void main(String[] args) {
    TrainManagementSystem tms = new TrainManagementSystem();

    Train train1 = new Train("G1234", "高铁", "一等座", "北京", "上海", 100);
    Train train2 = new Train("K5678", "普快", "硬座", "北京", "南京", 200);

    tms.addTrain(train1);
    tms.addTrain(train2);

    System.out.println(tms.getTrain("G1234").getTrainType());

    tms.removeTrain("K5678");

    Station station1 = new Station("北京", "08:00", "08:10");
    Station station2 = new Station("上海", "12:00", "12:10");

    tms.addStation(station1);
    tms.addStation(station2);

    System.out.println(tms.getStation("北京").getArriveTime());
}

这个简单的火车管理系统包括了火车信息和车站信息的添加、删除、查询和修改功能。你也可以根据你的需求进行修改和扩展。
