Java8中如何将IntStream转换为Integer[]呢?

IntStream转Integer

实现思路:
    1.使用IntStream boxed()转到Stream<Integer>
    2.将其转换为Array

package com.java265;
import java.util.Arrays;
import java.util.stream.IntStream;
import java.util.stream.Stream;
public class StreamExample { 
    public static void main(String[] args) {
 
        //int[] -> IntStream -> Stream<Integer> -> Integer[]
        int[] num = {888,999,1111};
 
        //1. int[] -> IntStream
        IntStream stream = Arrays.stream(num);
 
        //2. IntStream -> Stream<Integer>
        Stream<Integer> boxed = stream.boxed();
 
        //3. Stream<Integer> -> Integer[]
        Integer[] result = boxed.toArray(Integer[]::new);
 
        System.out.println(Arrays.toString(result));
 
        // one line
        Integer[] oneLineResult = Arrays.stream(num).boxed().toArray(Integer[]::new);
        System.out.println(Arrays.toString(oneLineResult));
    }
}
