Java Stream - 如何使用Integer :: min减少

import java.util.Arrays;
import java.util.List;
import java.util.Optional;

public class Main {
  public static void main(String...args){
    List<Integer> numbers = Arrays.asList(3,4,5,1,2);


    Optional<Integer> min = numbers.stream().reduce(Integer::min);
    min.ifPresent(System.out::println);
    
  }
}
