QUESTION
I'm streaming objects of a class implementing an interface. I'd like to collect them as a list of elements of the interface, rather than the implementing class.
This seems impossible with Java 16.0.1's Stream#toList
method. For example in the code below, the last statement will fail to compile.
ANSWER
Answered 2021-May-14 at 04:36Generic type argument resolution happens one method call at a time.
Stream.of(new FancyDodo())
will always resolved T
to FancyDodo
, so will always result in a Stream
.
toList()
doesn't resolve T
, it just uses the already-established T
, so the result is always List
, and List
is not compatible with List
. See: "Is List
a subclass of List
? Why are Java generics not implicitly polymorphic?"
collect(Collectors.toList())
has a different T
in the Collectors.toList()
, that can resolve differently from the T
of the Stream
. The compiler resolves that T
as Dodo
, because of the desired return type of List
.

QUESTION
I'm trying to improve code performance and after years of coding find myself confused about some fundamentals. Of course we essentially have things that need go in order (async functions) and things in parallel (just normal functions which are synchronous ). I read about promise.all and setTimeout type examples and tried to make a big function rewritten with all these fundamentals and was throwing async on every function and when I finished it was way slower than it was before and now am realizing that async is not as prevalent as I thought but am confused.
If I have the function
...ANSWER
Answered 2021-Feb-02 at 00:35Promises (and thus async/await) aren't a tool to take synchronous code and speed it up. When you create a promise it's usually because you're not calculating anything at all, but instead are waiting for something external to happen.
For example, you might be waiting for a network response to get back, or you might be waiting for a timer to elapse, or waiting for someone to press a key. You can't do any work while this is happening, so instead you create a Promise and then stop running any code. Since javascript is single threaded, stopping running your code is important to let other code start running, including the browser's normal page-painting code.
Promises are objects with .then
function on it. You can call .then
and pass in a function to tell it "hey, when you're done waiting, please call this function". async
/await
just simplifies the syntax for working with promises: an async
function will automatically create a promise, and await
ing a promise will automatically call .then
on it.
With that in mind: The examples you gave don't have anything to do with async await. You have a bunch of synchronous computations, and are not waiting for anything external. Slapping await on a map function or a for loop will have no effect, other than to confuse your coworkers and very slightly increase runtime.

...ANSWER
Answered 2020-Jul-19 at 10:46You are looking for auto-fit
, not auto-fill
:
I found a very good explanation on this here:
auto-fill
fills the row with as many columns as it can fit. So it creates implicit columns whenever a new column can fit, because it’s trying to fill the row with as many columns as it can. The newly added columns can and may be empty, but they will still occupy a designated space in the row.
auto-fit
fits the currently available columns into the space by expanding them so that they take up any available space. The browser does that after filling that extra space with extra columns (as withauto-fill
) and then collapsing the empty ones.

QUESTION
I am trying to generate an invoice based on the array of orders and outlets, to do that I have to go through outlets array and get the comission
as well as some other information and based on it I loop through the orders
array in order to do the necessary calculations; however it seems that I have a logical issue as I am trying to get the values needed on outlets
array which has a length of 2 and the length of orders
array is 3 so the orders
array is always not fully executed but stops at the second index.
The question : What should I do in order to list/calculate the final invoice for each store (id) ?

...ANSWER
Answered 2020-May-06 at 18:21You pass the itemsProcessed++
statement as a parameter to the forEach function, instead of using it in the forEach loop like you probably intended to do.
The forEach function is called twice, and so itemsProcessed is incremented twice.
