Code in Android Studio failed to display Array List

Question

I have been trying to create an output for an array list of API books using JSON object and this array code gives a hint not a statement. Below is the block of code in Java using Android Studio

Book book = new Book {
  bookJSON.getString(ID),
    volumeInfoJSON.getString(TITLE),
    (volumeInfoJSON.isNull(SUBTITLE)?"":volumeInfoJSON.getString(SUBTITLE)),
    authors, volumeInfoJSON.getString(PUBLISHER), 
    volumeInfoJSON.getString(PUBLISHED_DATE);

    books.add(book);
  }
}

Maybe you should change it like this?

Book book = new Book {
    bookJSON.getString(ID),
    volumeInfoJSON.getString(TITLE),
    (volumeInfoJSON.isNull(SUBTITLE)?"":volumeInfoJSON.getString(SUBTITLE)),
    authors, volumeInfoJSON.getString(PUBLISHER), 
    volumeInfoJSON.getString(PUBLISHED_DATE);
}
books.add(book);

The only difference is I put the books.add(book) statement out of new Book {} block.
