We have implemented PutResolver before and we have created a stub interface for the GetResolver. Here, we will finish the work that we have started by fully implementing the missing interface.

Let's create a class named StockUpdateGetResolver in the same package as StockUpdatePutResolver, which will extend the DefaultGetResolver class:

public class StockUpdateGetResolver extends DefaultGetResolver<StockUpdate> {
}

Next, add a missing implementation of mapFromCursor():

@NonNull
@Override
public StockUpdate mapFromCursor(@NonNull Cursor cursor) {

    final int id = cursor.getInt(cursor.getColumnIndexOrThrow
        (StockUpdateTable.Columns.ID));
    final long dateLong = cursor.getLong(cursor.getColumnIndexOrThrow
        (StockUpdateTable.Columns.DATE));
    final long priceLong = cursor.getLong(cursor.getColumnIndexOrThrow
        (StockUpdateTable.Columns.PRICE));
    final String stockSymbol =  
        cursor.getString(cursor.getColumnIndexOrThrow
            (StockUpdateTable.Columns.STOCK_SYMBOL));


    Date date = getDate(dateLong);
    BigDecimal price = getPrice(priceLong);

    final StockUpdate stockUpdate = new StockUpdate(
            stockSymbol,
            price,
            date
    );

    stockUpdate.setId(id);

return stockUpdate;
}

It's quite a big chunk of code, so let's dig into its pieces.
