JTextPaneでテキスト検索メカニズムを実装する方法は？

Question

私のJTextPaneでFindメカニズム（テキストエディタや単語のような）を実装したいと思います。 次の/前のオプション（上/下の矢印）を見つけて、見つかったすべての単語にハイライト表示します。 これを行う簡単な方法はありますか？

Answer 1

私は専門家ではないよ、私は次のコードの作業を発見した： -

public static void GetTextToFindAndFind(String textToFind, int ignorecase, int findCounter){ 
    // findCounter = 0 or 1. 0 represents find and 1 represents findCounter. 
    String Current2 = textPane.getText(); 
    if(findCounter ==0){ 

     if(textToFind == null){ 
      optionPane.showMessageDialog(null, "Please Enter Text.", "Error", 0); 
     } 
     else if(textToFind.isEmpty()){ 
      optionPane.showMessageDialog(null, "Please Enter Text.", "Error", 0); 
     } 
     else{ 
      // Use any Character. But I a suggest to use a character from an Encrypted file. 
      Replacer = "¥"; 
      CurrentText = textPane.getText(); 
      if(ignorecase==1){ 
       CurrentText = CurrentText.toLowerCase(); 
       textToFind = TextToFind.toLowerCase(); 
      } 
      int counter = 0; 
      readtext = new StringReader(CurrentText); 
      readBuffer = new BufferedReader(readtext); 
      try { 
       String Line = readBuffer.readLine(); 
       int found = 0; 
       while(Line!=null || found != 1){ 
        if(Line.contains(TextToFind)){ 
         Line = null; 
         found = 1; 
        } 
        if(Line!=null){ 
         Line = readBuffer.readLine(); 
         counter = counter + 1; 
        } 
       } 
       if(found == 1){ 
        textPane.setSelectionStart(CurrentText.indexOf(textToFind) - counter); 
        textPane.setSelectionEnd(CurrentText.indexOf(textToFind) + textToFind.length() - counter); 
        int counter2 = 1; 
        while(counter2!=textToFind.length()){ 
         Replacer = Replacer + "¥"; 
         counter2 = counter2 + 1; 
        } 
        CurrentText = CurrentText.replaceFirst(textToFind, Replacer); 
        findCounter = 1; 
          } 
       else{ 
        optionPane.showMessageDialog(null, "No Matches.", "Message", 0);  
        } 

       } 
       catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch(NullPointerException e){ 
       optionPane.showMessageDialog(null, "No Matches.", "Message", 0); 
      } 
      } 
     } 

    else{ 
     int counter = 0; 
     readtext = new StringReader(CurrentText); 
     readBuffer = new BufferedReader(readtext); 
     try { 
      String Line = readBuffer.readLine(); 
      int found = 0; 
      while(Line!=null || found != 1){ 
       if(Line.contains(textToFind)){ 
        Line = null; 
        found = 1; 
       } 
       if(Line!=null){ 
        Line = readBuffer.readLine(); 
        counter = counter + 1; 
       } 
      } 
      if(found == 1){ 
       textPane.setSelectionStart(CurrentText.indexOf(textToFind) - counter); 
       textPane.setSelectionEnd(CurrentText.indexOf(textToFind) + textToFind.length() - counter); 
       CurrentText = CurrentText.replaceFirst(textToFind, Replacer); 
         } 
      else{ 
       optionPane.showMessageDialog(null, "No Matches.", "Message", 0);  
       } 
      } 
      catch(IOException e){ 
       e.printStackTrace(); 
      } catch(NullPointerException e){ 
       optionPane.showMessageDialog(null, "No Matches.", "Message", 0);  
       } 
      } 
    }

JFindReplaceツールがあります。あなたは置換を無効にすることができ、ちょうど見つけることができますそれ以外に、私はそれがどれほど良いかわからない。
