在java中比较并提取两个数组中的相似字符串，双字不比较

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        String[] arr1 = {"apple", "banana", "cat", "dog"};
        String[] arr2 = {"banana", "dog", "elephant"};

        String[] result = compareAndExtractStrings(arr1, arr2);
        System.out.println(Arrays.toString(result));
    }

    public static String[] compareAndExtractStrings(String[] arr1, String[] arr2) {
        List<String> resultList = new ArrayList<>();

        for (String str1 : arr1) {
            for (String str2 : arr2) {
                if (str1.equals(str2)) {
                    if (str1.length() != 2) {
                        resultList.add(str1);
                    }
                }
            }
        }

        return resultList.toArray(new String[0]);
    }
}
