Android Studio - Ошибка при создании таблицы - Logcat

Question

DatabaseHelperClass. java

Это вспомогательный класс базы данных для создания базы данных в android. Но это не работает, как я вижу в android logcat. Невозможно указать столбец местоположения в базе данных. Пожалуйста, сообщите, если я допустил ошибку в следующих классах.

public class DatabaseHelperClass extends SQLiteOpenHelper {

    public static final int DATABASE_VERSION = 1;
    public static final String DATABASE_NAME = "metrolines.db";

    public DatabaseHelperClass(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        /* CREATE CLASS */
        db.execSQL(Station.CREATE_TABLE);

        Log.d("Create Table", "Passed this step");
        Insert_Station(new Station("Uttam Nagar East","West Delhi"));
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        /* DROP TABLE IF EXIST */
        db.execSQL("DROP TABLE IF EXISTS " + Station.TABLE_NAME);

        /* CREATE TABLES AGAIN */
        onCreate(db);
    }

    public void Insert_Station(Station station) {
        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues contentValues = new ContentValues();
        contentValues.put(Station.STATION_NAME, station.getD_Station());
        contentValues.put(Station.STATION_LOCATION, station.getD_Location());

        db.insert(Station.TABLE_NAME, null, contentValues);
        db.close();
    }

    public List<Station> getStationList() {
        List<Station> stationList = new ArrayList<Station>();

        //StationList
        String SELECT_QUERY = "SELECT * FROM " + Station.TABLE_NAME;
        SQLiteDatabase db = this.getWritableDatabase();
        Cursor cursor = db.rawQuery(SELECT_QUERY, null);

        if (cursor.moveToFirst()) {
            do {
                Station station = new Station();
                station.setD_Station(cursor.getString(1));
                station.setD_Location(cursor.getString(2));
                stationList.add(station);
            } while (cursor.moveToNext());
        }
        return stationList;
    }}

Станция. java

public class Station {
    public static final String TABLE_NAME = "STATION_TABLE";

    public static final String STATION_NAME = "Station_name" ;
    public static final String STATION_LOCATION = "Location_name" ;

    private String D_Station;
    private String D_Location;

    //create table SQL Query
    public static final String CREATE_TABLE =
            "CREATE TABLE STATION_TABLE (ID INTEGER PRIMARY KEY AUTOINCREMENT, Station_name TEXT, Location_name TEXT)";

    public Station(){

    }

    public Station(String d_Station, String d_Location) {
        D_Station = d_Station;
        D_Location = d_Location;
    }

    public String getD_Station() {
        return D_Station;
    }

    public void setD_Station(String d_Station) {
        D_Station = d_Station;
    }

    public String getD_Location() {
        return D_Location;
    }

    public void setD_Location(String d_Location) {
        D_Location = d_Location;
    }
}

MainActiviy. java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        DatabaseHelperClass db = new DatabaseHelperClass(this);

        Log.d("Insert", "Inserting");
        db.Insert_Station(new Station("Uttam Nagar East", "West Delhi"));
        db.Insert_Station(new Station("Dwarka Sec 9", "West Delhi"));
        db.Insert_Station(new Station("Rajiv Chowk", "Central Delhi"));
        db.Insert_Station(new Station("Hauz Khas", "South Delhi"));
