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?

[diesieben07]

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?

[rockerhieu]

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

[diesieben07]

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

[rockerhieu]

swallow the exception

[diesieben07]

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

[rockerhieu]

keep from, minimize to

[diesieben07]

And if from is out of bounds? 😄

[rockerhieu]

ok, let me change it to srcList.take(count)

[diesieben07]

take never throws 😉

[rockerhieu]

nice, let me check 👍
