public void testDialog() 
    { 
     JPanel myPanel = new JPanel(new GridBagLayout()); 
     GridBagConstraints grid = new GridBagConstraints(); 
     grid.gridx=0; //Moves Things across 
     grid.gridy=0; //Moves things down 
     myPanel.add(new JLabel("ENTER PLAYER NAMES", JLabel.CENTER), grid); 
     grid.gridy++; 
     JTextField tfNames [] = new JTextField[getNumOfPlayers()]; 
     //Loops through the number of players, initialising and adding a JLabel and JTextField to the JPanel 
     for(int i=0;i < getNumOfPlayers();i++) 
     { 
      grid.gridx = 0; 
      tfNames[i] = new JTextField(10); 
      myPanel.add(new JLabel("Player " + (i+1), JLabel.CENTER), grid); 
      grid.gridx ++; 
      myPanel.add(tfNames[i], grid); 
      grid.gridy+=1; 
     } 

     int result = JOptionPane.showConfirmDialog(null, myPanel, 
       "Initial Dialog", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null); 
     //Declaring the array of strings which holds the players name 
     playerNames = new String [getNumOfPlayers()]; 
     //If the 'OK' button is clicked loop through the number of players checking to see if all the JTextFields aren't empty 
     //If they are recall this method otherwise store the input player names in the playerName array. 
     if(result == JOptionPane.OK_OPTION) 
     { 
      for(int i=0;i < getNumOfPlayers();i++) 
      { 
       if(tfNames[i].getText().equals("")) 
       { 
        testDialog(); 
       } 
       else 
       { 
        playerNames[i] = tfNames[i].getText(); 
       } 
      } 
     } 
     //If 'Cancel' button is clicked go back to the previous dialog 
     else if (result == JOptionPane.CANCEL_OPTION) 
     { 
      numPlayersDialog(); 
     } 
     //If 'x' in top right hand corner of the screen is clicked go back to previous dialog 
     else 
     {

    } 

이 스타일을 사용하면 현재 고통을 느끼고 있습니다. Player1, Player2, Player3, Player4 JLabels을 JTextField와 함께 가운데에 배치하려고합니다. 또한 'Change Player Names'JLabel을 변경하여 변경 한 것 같습니다.
