第一次结对作业

今天将数据库连接后端创建了几个数据类，方便对数据进行读取等操作

package com.example.metro_info_front_end.DataModel;

import java.util.List;

public class MetroLine {
    private String lineNumber;
    private List<MetroStation> stations;

    public String getLineNumber() {
        return lineNumber;
    }

    public List<MetroStation> getStations() {
        return stations;
    }
}

package com.example.metro_info_front_end.DataModel;

import java.util.List;

public class MetroStation {
    private String stationName;
    private String stationCode;
    private Boolean isTransferStation;
    private List<String> lineNumbers;

    public String getStationName() {
        return stationName;
    }

    public String getStationCode() {
        return stationCode;
    }

    public Boolean isTransferStation() {
        return isTransferStation;
    }

    public List<String> getLineNumbers() {
        return lineNumbers;
    }
}

package com.example.metro_info_front_end.DataModel;
import java.util.List;

public class MetroSystem {
    private String systemName;
    private String systemCode;
    private List<MetroLine> lines;

    public String getSystemName() {
        return systemName;
    }

    public String getSystemCode() {
        return systemCode;
    }

    public List<MetroLine> getLines() {
        return lines;
    }
}
