在Java中删除数组中重复项的最佳方法是什么？

Set<Integer> set = new HashSet<>();

for (int num : array) {
    set.add(num);
}

Integer[] uniqueArray = set.toArray(new Integer[0]);

int[] result = Arrays.stream(uniqueArray).mapToInt(Integer::intValue).toArray();

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;

public class Main {
    public static void main(String[] args) {
        int[] array = {1, 2, 3, 4, 4, 5, 6, 6, 7};

        Set<Integer> set = new HashSet<>();

        for (int num : array) {
            set.add(num);
        }

        Integer[] uniqueArray = set.toArray(new Integer[0]);

        int[] result = Arrays.stream(uniqueArray).mapToInt(Integer::intValue).toArray();

        System.out.println(Arrays.toString(result));
    }
}

[1, 2, 3, 4, 5, 6, 7]
