如何在java中的字符串数组中找到唯一的元素？

import java.util.HashSet;

public class UniqueElements {
    public static String[] findUniqueElements(String[] array) {
        HashSet<String> uniqueSet = new HashSet<>();

        for (String element : array) {
            uniqueSet.add(element);
        }

        String[] uniqueArray = new String[uniqueSet.size()];
        uniqueSet.toArray(uniqueArray);

        return uniqueArray;
    }

    public static void main(String[] args) {
        String[] array = {"apple", "banana", "apple", "orange", "banana"};
        String[] uniqueElements = findUniqueElements(array);

        System.out.println("Unique elements:");
        for (String element : uniqueElements) {
            System.out.println(element);
        }
    }
}
