java - 如何以一种方法获取2个arraylist多数民众赞成的内容

我正在使用wearet3.0来获取每个单词的同义词和光泽....我附加了一段代码（一个搜索词方法），其中我有2个arraylist ..我需要返回2个arraylist操作...。我该怎么做？我试图使用map ...但是仍然我没有任何唯一的键可以这样做...任何人都给我一些主意，我该如何获取两个数组列表（nums和nums1）的内容

public ArrayList<String> searchWord(String key)
    {

    nums.clear();
            /*  A word is having a different WordId in different synsets. Each Word is having a
         *  unique Index.
        */

        //Get  the index associated with the word, 'book' with Parts of Speech NOUN.

        IIndexWord idxWord = idict.getIndexWord(key, POS.NOUN);
         if(idxWord==null)
                 {
                     return nums;
                 }
        System.out.println("Word ->"+key);
        System.out.println("-------------");
        System.out.println("-------------");

        int i=1;

        /*getWordIDs() returns all the WordID associated with a index
         *
         */
                IWord word;
                ISynset wordSynset = null;
                //if(StringUtils.isNotEmpty(idxWord.getWordIDs()))
        for(IWordID wordID : idxWord.getWordIDs())
        {
            //Construct an IWord object representing word associated with wordID
            word = idict.getWord(wordID);
            //System.out.println("SENSE->"+i);
            //System.out.println("---------");

                wordSynset = word.getSynset();

            System.out.print("Synset "+i+" {");

            //Returns all the words present in the synset wordSynset
            for(IWord synonym : wordSynset.getWords())
            {
                System.out.print(synonym.getLemma()+", ");
                                nums1.add(synonym.getLemma());
            }
            System.out.print("}"+"\n");

            nums.add(wordSynset.getGloss());
                        for(String s:nums)
//                      {
//                          System.out.print(s);
//                      }
            //Returns the gloss associated with the synset.
            System.out.println("GLOSS -> "+wordSynset.getGloss());

            System.out.println();
            i++;
                }
                        return nums;



                 //   WordNetDatabase database=WordNetDatabase.getFileInstance();
    }

最佳答案

您可以使用一个对象来保存/包装两个ArrayList：

public Something searchWord(final String key) {
    // ...
    return new Something(num1, num2);
}

与：

public class Something {
    private ArrayList<String> num;
    private ArrayList<String> num1;

    public Something(final List<String> num, final List<String> num1) {
        this.num = num;
        this.num1 = num1;
    }

    // getters, setters, ...
}

要么

使用Apache commons-lang中的Pair：

public Pair<List<String>, List<String>> searchWord(final String key) {
    // ...
    return new Pair<List<String>, List<String>>(num1, num2);
}
