I have a method (getContacts
) that returns a List<Contact>
and I need to convert this result to a MutableList<Contact>
. Currently the best way I can think of doing it is like this:
val contacts: MutableList<Contact> = ArrayList(presenter.getContacts())
Is there a more idiomatic/"less Java" way to do that?
Consider using the toMutableList()
function:
presenter.getContacts().toMutableList()
There are toMutableList()
extensions for the stdlib types that one might want to convert to a mutable list: Collection<T>
, Iterable<T>
, Sequence<T>
, CharSequence
, Array<T>
and primitive arrays.
