같은 것을보고 그 숫자는 사용자에게 편집되지 않은이됩니까?

import javax.swing.text.AttributeSet; 
import javax.swing.text.BadLocationException; 
import javax.swing.text.PlainDocument; 


public class Squares extends JPanel { 

    public final int CELL_COUNT = 9; 
    public Cell [] cells = new Cell[CELL_COUNT]; 

    public Squares(){ 
     this.setLayout(new GridLayout(3,3)); 
     this.setBorder(new LineBorder(Color.BLACK,2)); 
     for(int i = 0; i<CELL_COUNT; i++){ 
      cells[i] = new Cell(); 
      cells[i].setDocument(new NumericalDocument()); 
      this.add(cells[i]); 
     } 
    } 

    public class Cell extends JTextField{ 

     private int number; 
     public Cell(){ 

     } 
     public void setNumber(int number){ 
      this.number = number; 
      this.setText("5"); 
     } 
     public int getNumber(){ 

      return number; 
     } 

    } 

    public static class NumericalDocument extends PlainDocument{ 
     String numbers = ""; 
     public void insertString(int offs, String str, AttributeSet a) throws BadLocationException { 
      if (getLength() == 0 && str.length() == 1 && numbers.contains(str)) { 
       super.insertString(offs, str, a); 
      } 
      else { 
       Toolkit.getDefaultToolkit().beep(); 
      } 
     } 
    } 
} 

을하고 여기에 3 × 3 격자 JTextField가 setEditable(false)를 사용하여 편집 할 설정할 수 있습니다
