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";
       ...
   }
}

when i do

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
" )";

I am not able to use FeedEntry directly. I have to use FeedReaderContract.FeedEntry.COLUMN_NAME instead of FeedEntry.COLUMN_NAME. How to use FeedEntry directly??

It is basically a java question and not a question directly related to android. So it will be better if you can add the java tag. – Stanley Paul Sep 01 '15 at 10:28
ok done now can you help me with the answer? – anupam x Sep 01 '15 at 10:33
`import static FeedReaderContract.FeedEntry;` – JimmyB Sep 01 '15 at 10:43
yeah thanks it worked – anupam x Sep 01 '15 at 10:51
Btw, your comment `To prevent someone from accidentally instantiating the contract class, give it an empty constructor.` does not seem to make sense. You probably want a `private` constructor here. – JimmyB Sep 01 '15 at 14:26
