如何将我的 JTextField 居中对齐

Question

所以我有两个面板，第一个包含文本字段和标签：

public class Panel1 extends JFrame implements ActionListener {


//Common variables

    JTextField val;



public Component panel1() {

    // Panel 1 to add labels and textfields

    final JPanel order = new JPanel(new GridLayout(1, 5));{

      order.add(new JLabel("Current Value:", JLabel.CENTER));
      order.add(val = new JTextField(3));

另一个包含按钮的面板：

     JPanel buttons = new JPanel();


      JButton add;
      buttons.add(add=new JButton("+"));
    add.setToolTipText("Pressing the button will find total cost");


      add.addActionListener(new ActionListener() 
      {
        @Override
        public void actionPerformed(ActionEvent e) 
        {
            // TODO Auto-generated method stub


        }

      });

      JButton sub;
      buttons.add(sub = new JButton("-"));
      sub.setToolTipText("Pressing the button will save the record to .csv file");

      sub.addActionListener(new ActionListener()
    {
        @Override
        public void actionPerformed(ActionEvent e) { 


            }   

        });



      JButton reset;
      buttons.add(reset=new JButton("Clear"));
    reset.setToolTipText("Pressing the button will clear data entered into the screen");

      reset.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            // TODO Auto-generated method stub



        }   
        });

      JButton quit;
      buttons.add(quit= new JButton("Quit"));
    quit.setToolTipText("Pressing the button will close the window");

       quit.addActionListener(new ActionListener()
       {

    @Override
    public void actionPerformed(ActionEvent e) 
    {
        // TODO Auto-generated method stub
      System.exit(0);

    }


    });



    // Panel to combine rest of the panels to one
    JPanel main = new JPanel();
    main.setLayout(new GridBagLayout());
    main.add(order);
    main.add(buttons);

    return main;}
}
@Override
public void actionPerformed(ActionEvent arg0) {
    // TODO Auto-generated method stub

}


}

问题是我的文本域没有对齐。 IT SIS 排成一排，按钮如下：

                _______    ________     ________    _______  
 Current Value:|_______|   |____+___|  |___-____|  |__reset|

我希望 Jtextfield（当前值）位于中间，而不是按钮。

使用另一个布局管理器。

尝试替换

JPanel order = new JPanel(new GridLayout(1, 5));

和

JPanel order = new JPanel(new FlowLayout());
