Call constructor with parameter inside Java stream with lambda

Question

I want to call a constructor for MySortedSet that takes in a Comparator c as a parameter. How can I modify this to do so?

public MySortedSet subSet(         


        

Answer 1

You can’t use method references if you want to pass additional captured values as parameters. You will have to use a lambda expression instead:

MySortedSet<E> :: new

=>

() -> new MySortedSet<E>(c)
