从数组中删除重复的字符串？

尝试使用以下代码删除重复的单词：

StringBuilder sb = new StringBuilder();for (int i = 0; i < wordList.length; i++) {    boolean found = false;    for (int j = i+1; j < wordList.length; j++) {        if (wordList[j].equals(wordList[i])) { found = true; break;        }    }    // System.out.printf("Checking: [%s]%n", wordList[i]);    if (!found) {        if (sb.length() > 0) sb.append(' ');        sb.append(wordList[i]);    }}System.out.printf("Unique: [%s]%n", sb);
