Question

这是我的代码，它读取两个文件，一个带有单词，另一个带有乱码。程序读取并将加扰的字母与文件中的单词匹配。它工作但我希望输出按字母顺序排列。在我的代码中我可以进行排序吗？

#i_frame {
    display: none;
}

输出：

import java.io.*; import java.util.*; public class Tester { public static void main(String args[]) throws Exception { BufferedReader dictionary = new BufferedReader( new FileReader(args[0]) ); BufferedReader jumbles = new BufferedReader( new FileReader(args[1]) ); HashMap<String, List<String>> lookup = new HashMap<String, List<String>>(); while(dictionary.ready()) { String word = dictionary.readLine(); addWord(word, lookup); } dictionary.close(); while(jumbles.ready()) { String jWord = jumbles.readLine(); List<String>dWords= lookup.get(createKey(jWord)); String wordsString = Arrays.toString(dWords.toArray()).replace("[", "").replace("]", "").replace(",", "").trim(); if(dWords != null){ System.out.println(jWord + " " + wordsString); } } jumbles.close(); } private static String createKey(String word) { char[] cword = word.toCharArray(); Arrays.sort(cword); return new String(cword); } private static void addWord(String word, Map<String, List<String>> lookup) { String key = createKey(word); List<String> list = lookup.get(key); if(list == null) { list = new ArrayList<String>(); lookup.put(key, list); } list.add(word); } }

我想要的是什么：

atc act cat tac otsp post pots stop spot tops opts gdo dog god atr rat tar art arpt trap tarp part grof frog sylogs glossy

没关系。

修正了：

arpt part tarp trap
atc act cat tac
atr art rat tar
gdo dog god
grof frog
otsp opts post pots spot stop tops
sylogs glossy

您可以创建字符串列表然后对它们进行排序

    List<String> result = new ArrayList<>();
    while(jumbles.ready())
    {
        String jWord = jumbles.readLine();
        List<String>dWords= lookup.get(createKey(jWord));
        String wordsString = Arrays.toString(dWords.toArray()).replace("[", "").replace("]", "").replace(",", "").trim();


        if(dWords != null){
            result.add(jWord + " " + wordsString);
        }
    }
    jumbles.close();
    result.sort(String::compareTo);
    result.forEach(System.out::println);

按字母顺序排序HashMap程序的输出
