如果满足条件，则if语句未打印出正文

Question

我希望输出将是在forList退出之前与搜索匹配的wordList中的字符串，但是当if语句满足条件时，它不会每次输出。

search =“ ABC”
wordList = [[“ ABC”，“ 123”]，[“ ABC”，“ 456”]，[“ DEF”，“ 123”]]

public void biDi(String searchWord, String[][] wordList) {
    int start = 0; 
    int end = list.size ()-1;
    String search = searchWord;

    int path = 0;
    for (int i = 0; (i < (list.size ()/2)); i++) {
        if (search == wordList[start][0]) {
            System.out.println (wordList[start][1]);
        }
        if (search == wordList[end][0]) {
            System.out.println (wordList[end][1]);
        }

        start++;
        end--;
        path++;
    }

    System.out.println (path);

}

您需要使用equals而不是==，在字符串比较参考而非值上使用==。

if (search.equals(wordList[start][0])) {
    System.out.println(wordList[start][1]);
} 
if (search.equals(wordList[end][0])) {
    System.out.println(wordList[end][1]);
}
