Java Stream - 如何将列表转换为流

import java.util.Arrays;
import java.util.List;
import java.util.stream.Stream;

public class Main {
   public static void main(String[] args) {
     List<Integer> numberList = Arrays.asList(1, 2, 3, 4, 5);
     Stream<Integer> listStream = numberList.stream();

     System.out.println(Arrays.toString(listStream.toArray()));
   }

}
