JTree, много записей

1 голос
/ 01 января 2012

Так что я привык создавать JTree, добавляя DefaultMutableTreeNode к своей модели, но сейчас у меня есть много записей, которые относятся к 1 JTree, есть более короткий способ сделать это, например, вы делаете JList, где вы можете просто указать String table[] = {};

Так что это прямо из моего старого JList. JTree должно выглядеть так: Строка, содержащая тег "html", должна быть узлом PARENT, а один отступ должен быть CHILD

Так должно выглядеть так:

  • Щит трудолюбивых <Родитель </li>
  • >>> Баллистическая отклоняющая матрица
  • >>> Матрица демпфирования взрыва

Я попытался поместить это в файл, проанализировать его и распечатать узлы следующим образом: 

public class Env {
    public static void main(String[] args)
    {           
        try {
            Scanner input   = new Scanner(new File("data.txt"));
            String line;
            String sub;
            while(input.hasNextLine())
            {
                line = input.nextLine();

                String subline = line.replace('"', ' ').substring(11).replace("</b> </html> ,", " ").trim().replace(" ", "_");
                if(line.contains("<html>")){
                    System.out.println("DefaultMutableTreeNode " + subline + " = new DefaultMutableTreeNode(" + line.replace(",", " ").trim() + ");");
                } 
            }

        } catch (Exception e) {}
    }
}

Прежде чем я закончу писать этот код, есть более простой способ сделать это.

Я могу думать только об использовании регулярных выражений для «упрощения» замены String, но даже это вопрос мнения. 

import java.util.Scanner;

public class TestFoo {
   private static final String FILE_NAME = "data.txt";
   private static final String REGEX = "</?html>|</?b>|\"|,";

   public static void main(String[] args) {
      Scanner scan = new Scanner(new File(FILE_NAME));
      while (scan.hasNextLine()) {
         String line = scan.nextLine();
         String newLine = line.replaceAll(REGEX, "").trim();
         if (line.contains("html")) {
            System.out.println("Default Mut: " + newLine);
         } else {
            System.out.println("\t" + newLine);
         }
      }
   }
}

Конечно, вам понадобится попробовать / поймать, и не стоит игнорировать блок catch. Это также удалит запятые внутри кавычек и поэтому не является идеальным. Для загрузки доступны онлайн-библиотеки Java, которые позволяют очень аккуратно разбирать файлы, разделенные запятыми.

НЕТ КОРОТКОГО ПУТИ Проблема решена путем анализа данных, как показано ниже, путем добавления else для дочерних узлов.
