Question

我写不出正确的话。我怎么能解决这个问题？我想要这样的东西：

    <text><sentence>
    <word>a</word>
    <word>had</word>
    <word>lamb</word>
    <word>little</word>
    <word>Mary</word>
</sentence>
<sentence>
    <word>Aesop</word>
    <word>and</word>
    <word>called</word>
    <word>came</word>
    <word>for</word>
    <word>Peter</word>
    <word>the</word>
    <word>wolf</word>
</sentence>
<sentence>
    <word>Cinderella</word>
    <word>likes</word>
    <word>shoes</word>
</sentence>

但我有这样的事情：

<text>
    <sentence>
        <word>a</word>
        <word>had</word>
        <word>lamb</word>
        <word>little</word>
        <word>Mary</word>
    </sentence>
</text>

问题出在initItems，由于语句return nexSplit;（在内循环中），在第一句之后返回。您必须将一个句子的已排序单词收集到一个List中，然后返回该列表。我重复了方法initItems中需要更改的行：

 public static List<String[]> initItems() {  // RETURN A LIST
     List<String[]> sents = new ArrayList<>();  // declare new List
     // ...
         for (int i = 0; i < splitText.length; i++) {
              nexSplit = splitText[i].split("[ \t]");
              Arrays.sort(nexSplit, String.CASE_INSENSITIVE_ORDER);
              sents.add( nexSplit );  // APPEND WORDS OF ANOTHER SENTENCE
         }

    return sents;  // RETURN THE LIST OF WORDS-OF-A-SENTENCE
}

当然，主程序现在必须处理List<String[]>。
