What is the shortest & safest way to add items from a subList to another list?

srcList.subList(from, to).mapTo(destList) { convert(it) }

subList

may throw IndexOutOfBound, doesn't it?

Not sure what you are trying to achieve, do you want

to

and

from

to be constrained to the list's size automatically if they are too large?

I just want to make the above line more concise without raising IndexOutOfBoundException

What do you want to happen in case the indices are out of bounds though?

swallow the exception

Yes, but what should the value of the expression be?

keep

from

, minimize

to

And if

from

is out of bounds? 😄

ok, let me change it to

srcList.take(count)

take

never throws 😉

nice, let me check 👍
