Alternate code confusion

QMoney Module 2
#1

Instead of this (as given in FAQ) : List collection = mapper.readValue(result,
new TypeReference<ArrayList>() {
});

If I use : TiingoCandle[] collection = mapper.readValue(result, TiingoCandle[].class);

Is it alright?

#2

Its perfectly alright
I would give a small suggestion.
Store the output as list of candles
I.e List< Candle >
Before that you have to wrap the mapper.readValue with Array.asList(mapper.readValue(your arguments))
And store the output from above in list of candles
You are good to go

#3

I dont understand the wrapping part?

#4

Try it out first by yourself.
You will understand why I am saying to wrap it.

#5

I dont understand what is meant by wrapping here?

#6

Ok
Wrapping means paste your current function inside another function

#7

Here I have to use List(candle) or List(TiingoCandle) ?

#8

You are asking both the same

#9

Treat () as <>

Angle brackets are not displaying here. I dont know why?

#10

Looks like you are unfamiliar with Java
I will suggest you to practice Java before attempting the modules.
Otherwise there would be a great difficulty in next modules

#11

I know its the case of interface here. So, both should work fine right?

#12

Ya both will work. YOU CAN CHOOSE ANY OF THE ABOVE

Another doubt please - when I get an array of tingocandle for a particular symbol, which value to choose(as there are lot of them)?
