If statement does not print out the body when the condition has met

Question

I expect the output will be the string in the wordList when it matched the search before the for loop exits but it does not print out every time when the if statements met the condition.

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);

}

You are comparing your Strings wrong. You need to compare using the equals method — Stultuske, Jan 22 '19 at 07:16

You need to to use equals instead of ==, using == on string compare reference, not value.

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