Shortest code for assigning values to a List
-1
What could be the shortest possible code for this:
public void update(final Product object, final Callback<Product> callback) {
if(object.getIsDayDependent()) {
Double priceDay0 = object.getSundayPrice();
Double priceDay1 = object.getMondayPrice();
Double priceDay2 = object.getTuesdayPrice();
Double priceDay3 = object.getWednesdayPrice();
Double priceDay4 = object.getThursdayPrice();
Double priceDay5 = object.getFridayPrice();
Double priceDay6 = object.getSaturdayPrice();
List<DayPrice> dayPrices = new LinkedList<>();
dayPrices.add(new DayPrice(0, priceDay0));
dayPrices.add(new DayPrice(1, priceDay1));
dayPrices.add(new DayPrice(2, priceDay2));
dayPrices.add(new DayPrice(3, priceDay3));
dayPrices.add(new DayPrice(4, priceDay4));
dayPrices.add(new DayPrice(5, priceDay5));
dayPrices.add(new DayPrice(6, priceDay6));
object.setDayDependent(dayPrices);
} else {
object.setPrice(null);
object.setDayDependent(new LinkedList<>());
}
callback.onSuccess(object);
}

I'm guessing you cannot modify theProductclass, is that correct?

Well you could avoid all those local variables usingdayPrices.add(new DayPrice(0, object.getSundayPrice()))for example. But if you could addProduct.getPrice(int day)or similar, that would help a lot too...

How aboutList<DayPrice> dayPrices = Arrays.asList(new DayPrice(0, object.getSundayPrice()), new DayPrice(1, object.getMondayPrice()),...)? But why are you not using the callback argument in your method? What's its purpose?

@KevinO I can modify Product class somehow, what is your suggestion, maybe that's something that can be worked out in the Product class.

The following doesn't minimize code as much as it reduces the number statements, but it also eliminates unnecessary variables:
if(object.getIsDayDependent()) {
List<Double> prices = Arrays.asList(object.getSundayPrice(),
object.getMondayPrice(),
object.getTuesdayPrice(),
object.getWednesdayPrice(),
object.getThursdayPrice(),
object.getFridayPrice(),
object.getSaturdayPrice());
object.setDayDependent(IntStream.range(0, 7)
.mapToObj(i -> new DayPrice(i, prices.get(i)))
.collect(Collectors.toCollection(LinkedList<Double>::new)));
} else {
object.setPrice(null);
object.setDayDependent(new LinkedList<>());
}

Not much, but maybe there's some more clever way that someone can answer.

How about
List<DayPrice> dayPrices = Arrays.asList(new DayPrice(0, object.getSundayPrice()), new DayPrice(1, object.getMondayPrice()),...)? But why are you not using the callback argument in your method? What's its purpose?– SpiderPig

@KevinO I can modify Product class somehow, what is your suggestion, maybe that's something that can be worked out in the Product class.
