Question

我有一些代码用于按字母顺序排列三个单词。我正在尝试删除底部的方法，只需将其添加到上面的代码中。但是，我无法找到一种可行的方法。任何指导或帮助将不胜感激，谢谢！

    System.out.print("Please enter three words: ");
    final String words = keyboard.nextLine();
    final String[] parts = words.split(" ");

    if (parts[0].equals(parts[1]) && parts[1].equals(parts[2])) {
    System.out.println("All three of those words are the same!");

 } else  {

         System.out.print("In alphabetical order those are: ");
         alphabetizing (parts);
         final int three = 3;
         for (int limit = 0;  limit < three;  limit++) {
         System.out.print(parts[limit] + " ");
         }
  }
  }

  public static void alphabetizing (final String[]  parts) {
        int word;
        boolean check = true;
        String temp;

              for (word = 0;  word < parts.length - 1;  word++) {
                      if (parts[ word ].compareToIgnoreCase(parts[word + 1]) > 0) {
                                  temp = parts[word];
                                  parts[word] = parts[word + 1];
                                  parts[word + 1] = temp;
                                  check = true;

                      }
              }
        }
  }

因为你还是想做。我没有看到任何问题，为什么它不起作用。只需将其添加到您调用方法的else语句中，它应该可以工作。

    System.out.print("Please enter three words: ");
    Scanner keyboard = new Scanner(System.in);
    final String words = keyboard.nextLine();
    final String[] parts = words.split(" ");

    if (parts[0].equals(parts[1]) && parts[1].equals(parts[2])) {
        System.out.println("All three of those words are the same!");

    } else {

        System.out.print("In alphabetical order those are: ");

        //boolean check = true; you don't neeed this.
        String temp = "";

        for (int word = 0; word < parts.length - 1; word++) {
            if (parts[word].compareToIgnoreCase(parts[word + 1]) > 0) {
                temp = parts[word];
                parts[word] = parts[word + 1];
                parts[word + 1] = temp;

            }
        }
        final int three = 3;
        for (int limit = 0; limit < three; limit++) {
            System.out.print(parts[limit] + " ");
        }

    }

输出：

Please enter three words: a b c
In alphabetical order those are: a b c 
Please enter three words: a a a
All three of those words are the same!
