如何在其他JTextField下定位JTextField？

import javax.swing.*;
import java.awt.*;

public class JTextFieldPositioningExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("JTextField Positioning Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        JPanel panel = new JPanel();
        panel.setLayout(new GridLayout(2, 1)); // 使用GridLayout布局管理器，2行1列
        
        JTextField textField1 = new JTextField("TextField 1");
        JTextField textField2 = new JTextField("TextField 2");
        
        panel.add(textField1);
        panel.add(textField2);
        
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
    }
}
