no such column: useradd (code 1): , while compiling: SELECT uid,username,usertype,sex,usercompany,usermail,usercontact,useradd FROM User WHERE uid=?

I don't know why this error is appearing.. android.database.sqlite.SQLiteException: no such column: useradd (code 1): , while compiling: SELECT uid,username,usertype,sex,usercompany,usermail,usercontact,useradd FROM User WHERE uid=?

this is my code for crud

public class UserCrud {
private DBHelper dbHelper;

public UserCrud(Context context){
    dbHelper = new DBHelper(context);
}

public int insert(User user){
    SQLiteDatabase db = dbHelper.getWritableDatabase();
    ContentValues values = new ContentValues();
    values.put(User.KEY_ID, user.user_ID);
    values.put(User.KEY_username, user.user_name);
    values.put(User.KEY_usertype, user.usertype);
    values.put(User.KEY_sex, user.sex);
    values.put(User.KEY_usercompany, user.usercompany);
    values.put(User.KEY_usermail, user.usermail);
    values.put(User.KEY_usercontact, user.usercontact);
    values.put(User.KEY_useradd, user.useradd);

    long user_Id = db.insert(Project.TABLE, null, values);
    db.close();

    return (int) user_Id;

}

public void delete(int user_Id) {

    SQLiteDatabase db = dbHelper.getWritableDatabase();
    db.delete(Project.TABLE, Project.KEY_ID + "=?", new String[]{ String.valueOf(user_Id) });
    db.close();
}

public void update(User user){
    SQLiteDatabase db = dbHelper.getWritableDatabase();
    ContentValues values = new ContentValues();

    values.put(User.KEY_ID, user.user_ID);
    values.put(User.KEY_username, user.user_name);
    values.put(User.KEY_usertype, user.usertype);
    values.put(User.KEY_sex, user.sex);
    values.put(User.KEY_usercompany, user.usercompany);
    values.put(User.KEY_usermail, user.usermail);
    values.put(User.KEY_usercontact, user.usercontact);
    values.put(User.KEY_useradd, user.useradd);

    db.update(User.TABLE, values, User.KEY_ID + "= ?", new String[]{String.valueOf(user.user_ID)});
    db.close();
}

public ArrayList<HashMap<String, String>> getUserList (){
    SQLiteDatabase db = dbHelper.getReadableDatabase();

    String selectQuery = "SELECT " +
            User.KEY_ID + "," +
            User.KEY_username + "," +
            User.KEY_usertype + "," +
            User.KEY_sex + "," +
            User.KEY_usercompany + "," +
            User.KEY_usermail + "," +
            User.KEY_usercontact + "," +
            User.KEY_useradd +
            " FROM " + User.TABLE;

    ArrayList<HashMap<String, String>> userList = new ArrayList<HashMap<String, String>>();

    Cursor cursor= db.rawQuery(selectQuery, null);

    if (cursor.moveToFirst()){
        do {
            HashMap<String , String > user = new HashMap<String, String >();
            user.put("uid", cursor.getString(cursor.getColumnIndex(User.KEY_ID)));
            user.put("username", cursor.getString(cursor.getColumnIndex(User.KEY_username)));
            userList.add(user);

        } while (cursor.moveToNext());
    } cursor.close();
    db.close();
    return userList;
}

public User getUserById(int uId){
    SQLiteDatabase db = dbHelper.getReadableDatabase();

    String selectQuery = "SELECT " +
            User.KEY_ID + "," +
            User.KEY_username + "," +
            User.KEY_usertype + "," +
            User.KEY_sex + "," +
            User.KEY_usercompany + "," +
            User.KEY_usermail + "," +
            User.KEY_usercontact + "," +
            User.KEY_useradd +
            " FROM " + User.TABLE
            + " WHERE " +
            User.KEY_ID + "=?";

    int ictr =0;
    User user = new User();

    Cursor cursor = db.rawQuery(selectQuery, new String[]{ String.valueOf(uId)});

    if (cursor.moveToFirst()){
        do{
            user.user_ID=cursor.getInt(cursor.getColumnIndex(User.KEY_ID));
            user.user_name=cursor.getString(cursor.getColumnIndex(User.KEY_username));
            user.usertype=cursor.getString(cursor.getColumnIndex(User.KEY_usertype));
            user.sex=cursor.getString(cursor.getColumnIndex(User.KEY_sex));
            user.usercompany=cursor.getString(cursor.getColumnIndex(User.KEY_usercompany));
            user.usermail=cursor.getString(cursor.getColumnIndex(User.KEY_usermail));
            user.usercontact=cursor.getInt(cursor.getColumnIndex(User.KEY_usercontact));
            user.useradd=cursor.getString(cursor.getColumnIndex(User.KEY_useradd));
        }while (cursor.moveToNext());
    }cursor.close();
    db.close();
    return user;

}

 }

and this is for the table of User

public class User {
public static final String TABLE = "User";


// Labels Table Columns names
public static final String KEY_ID = "uid";
public static final String KEY_username = "username";
public static final String KEY_usertype = "usertype";
public static final String KEY_sex = "sex";
public static final String KEY_usercompany = "usercompany";
public static final String KEY_usermail = "usermail";
public static final String KEY_usercontact = "usercontact";
public static final String KEY_useradd = "useradd";


// property help us to keep dataS
public int user_ID;
public String user_name;
public String usertype;
public String sex;
public String usercompany;
public String usermail;
public int usercontact ;
public String useradd;

}

and this is how i created the table for user on my DBHelper extends SQLiteOpenHelper

  String CREATE_TABLE_USER = "CREATE TABLE " + User.TABLE + "("
            + User.KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT,"
            + User.KEY_username + " TEXT,"
            + User.KEY_usertype + " TEXT,"
            + User.KEY_sex + " TEXT,"
            + User.KEY_usercompany + " TEXT,"
            + User.KEY_usermail + " TEXT,"
            + User.KEY_usercontact + " INTEGER,"
            + User.KEY_useradd + " TEXT" + ");";

    db.execSQL(CREATE_TABLE_USER);
