这段代码有没有裸机或者语法错误public class MyDatabaseHelper extends SQLiteOpenHelper { public static String CREATE_PATIENT = "create table Patient(" + "id integer primary key," + "password text not null," + "phone integer not null," + "name text," + "gender text," + "age integer," + "doctor_id integer," + "alarm bool)"; public static String CREATE_DOCTOR = "create table Doctor(" + "doctor_id integer primary key," + "password text not null," + "phone integer not null)"; private Context mContext; public MyDatabaseHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version){ super(context, name, factory, version); mContext = context; } @Override public void onCreate(SQLiteDatabase db) { db.execSQL(CREATE_PATIENT); db.execSQL(CREATE_DOCTOR); ToastUtil.showMsg(mContext, "Create succeeded!"); } @Override public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) { } }

java面试题及答案(基础题122道,代码题19道).docx
这段代码没有显式的裸机错误或语法错误。不过,需要注意的是:
1. 该代码创建了两个表:Patient和Doctor,其中Patient表包含8个列,Doctor表包含3个列。
2. Patient表的id列被定义为主键,并且是整数类型。
3. Patient表的password和phone列不能为空。
4. Patient表的alarm列是布尔类型。
5. onUpgrade方法没有被实现,如果需要升级数据库版本,则需要在该方法中进行相应的处理。
如果使用该代码创建数据库,需要确保创建表的语句和表的列定义符合实际需求。
