Java9のStreamAPIでcollect（）メソッドを使用するにはどうすればよいですか？

構文

<R, A> R collect(Collector<? super T,A,R> collector)

例

import java.util.*;
import java.util.stream.*;

public class StreamCollectMethodTest {
   public static void main(String args[]) {
      List<String> list = List.of("a", "b", "c", "d", "e", "f", "g", "h", "i");

      List<String> subset1 = list.stream()
                                 .takeWhile(s -> !s.equals("e"))
                                 .collect(Collectors.toList());
      System.out.println(subset1);

      List<String> subset2 = list.stream()
                                 .dropWhile(s -> !s.equals("e"))
                                 .collect(Collectors.toList());
      System.out.println(subset2);

      List<Integer> numbers = Stream.iterate(1, i -> i <= 10, i -> i+1)
                                    .collect(Collectors.toList());
      System.out.println(numbers);
   }
}

出力

[a, b, c, d]
[e, f, g, h, i]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
