Cannot access string from another class?

I am following a tutorial on the android site. http://ift.tt/1hyiL4m

SQL_DATA_ENTRIES is lit up in red in FeedReaderDbHelper. How do I access it from FeedReaderDbHelper? Do I go with getters and setters or is there a better way?

//FeedReaderDbHelper

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

/**
 * Created by Neil Armstrong on 6/5/2015.
 */
public class FeedReaderDbHelper extends SQLiteOpenHelper  {
    // If you change the database schema, you must increment the database version.
    public static final int DATABASE_VERSION = 1;
    public static final String DATABASE_NAME = "FeedReader.db";

    public FeedReaderDbHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }
    public void onCreate(SQLiteDatabase db) {
        db.execSQL(SQL_CREATE_ENTRIES);
    }
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // This database is only a cache for online data, so its upgrade policy is
        // to simply to discard the data and start over
        db.execSQL(SQL_DELETE_ENTRIES);
        onCreate(db);
    }
    public void onDowngrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        onUpgrade(db, oldVersion, newVersion);
    }
}

//FeedReaderContract

import android.provider.BaseColumns;

/**
 * Created by Neil Armstrong on 6/5/2015.
 */
public final class FeedReaderContract {
    // To prevent someone from accidentally instantiating the contract class,
    // give it an empty constructor.
    public FeedReaderContract() {}

    /* Inner class that defines the table contents */
    public static abstract class FeedEntry implements BaseColumns {
        public static final String TABLE_NAME = "entry";
        public static final String COLUMN_NAME_ENTRY_ID = "entryid";
        public static final String COLUMN_NAME_TITLE = "title";
        public static final String COLUMN_NAME_SUBTITLE = "subtitle";
        private static final String TEXT_TYPE = " TEXT";
        private static final String COMMA_SEP = ",";
        private static final String SQL_CREATE_ENTRIES =
                "CREATE TABLE " + FeedEntry.TABLE_NAME + " (" +
                        FeedEntry._ID + " INTEGER PRIMARY KEY," +
                        FeedEntry.COLUMN_NAME_ENTRY_ID + TEXT_TYPE + COMMA_SEP +
                        FeedEntry.COLUMN_NAME_TITLE + TEXT_TYPE + COMMA_SEP +
         // Any other options for the CREATE command
                " )";

        private static final String SQL_DELETE_ENTRIES =
                "DROP TABLE IF EXISTS " + FeedEntry.TABLE_NAME;

    }
}
