Question

public static void main(String args[]) throws FileNotFoundException {
  Scanner LyricsFile = new Scanner(new FileReader("C:/Users/xxxx/Desktop/lyrics.txt"));
  ArrayList<String> LyricsList = new ArrayList<String>();
  while (LyricsFile.hasNext()) {
    String lyricssArray[] = LyricsFile.nextLine().split(" ");

    for (String str : lyricssArray) {
      LyricsList.add(str.replaceAll(",|\\.", ""));
    }
    String[] pangalanStrArray = {"Gagamba", "Araw", "Sanga", "Ulan"};
    String[] panghalipStrArray = {"sila"};
    String[] pangatnigArray = {"At"};
    String[] pandiwaArray = {"Umakyat", "Itinaboy", "Dumating"};
    String[] pangUriStr = {"palaging", "natuyo", "maliliit", "masaya"};
    String[] pangAbayArray = {};
    String[] pangUkolArray = {};
    String[] pangAwiArray = {};
    String[] pangAngkopArray = {"Na"};
    String[] pantukoyArray = {"Ang"};

    ArrayList<String> pangngalan = new ArrayList<String>();
    for (String name : LyricsList) {
      for (String compare : pangalanStrArray) {
        if (name.equalsIgnoreCase(compare) && !pangngalan.contains(compare.toLowerCase())) {
          pangngalan.add(name.toLowerCase());
          break;
        }
      }
    }
    System.out.println("1.Pangngalan: " + pangngalan);
    // break;
  }
}

输出如下：

1.Pangngalan: [gagamba, sanga]
1.Pangngalan: [gagamba, sanga, ulan]
1.Pangngalan: [gagamba, sanga, ulan, araw]
1.Pangngalan: [gagamba, sanga, ulan, araw]

但我只需要这个：

1.Pangngalan: [gagamba, sanga, ulan, araw]

请帮助:(它有点奇怪，我不知道如何删除重复:(它工作正常，但我试图再次运行它，它变得那样。我没有＆＃ 39;甚至添加或删除任何东西:(

修改我试着按照你们的建议去做，但是它给打印行造成了错误，错误说“PANGNGALAN”无法解析为变量＆＃39;

你在while循环中有你的print语句。因此它将在每次迭代中打印。所以移动这一行：

System.out.println("1.Pangngalan: "+  pangngalan);

在while循环的括号之外。您还必须在while循环之前定义列表。然后你的代码将如下所示：

public static void main(String args[]) throws FileNotFoundException {
    Scanner LyricsFile = new Scanner(new FileReader("C:/Users/xxxx/Desktop/lyrics.txt"));
    ArrayList<String> LyricsList = new ArrayList<String>();
    ArrayList<String> pangngalan = new ArrayList<String>();
    while (LyricsFile.hasNext()) {
        String lyricssArray[] = LyricsFile.nextLine().split(" ");

        for (String str : lyricssArray) {
            LyricsList.add(str.replaceAll(",|\\.", ""));
        }
        String[] pangalanStrArray = {"Gagamba", "Araw", "Sanga", "Ulan"};
        String[] panghalipStrArray = {"sila"};
        String[] pangatnigArray = {"At"};
        String[] pandiwaArray = {"Umakyat", "Itinaboy", "Dumating"};
        String[] pangUriStr = {"palaging", "natuyo", "maliliit", "masaya"};
        String[] pangAbayArray = {};
        String[] pangUkolArray = {};
        String[] pangAwiArray = {};
        String[] pangAngkopArray = {"Na"};
        String[] pantukoyArray = {"Ang"};

        for (String name : LyricsList) {
            for (String compare : pangalanStrArray) {
                if (name.equalsIgnoreCase(compare) && !pangngalan.contains(compare.toLowerCase())) {
                    pangngalan.add(name.toLowerCase());
                    break;
                }
            }
        }
    }
    System.out.println("1.Pangngalan: " + pangngalan);
}

Java重复循环输出
