用户窗口界面将三个信息用GridBagLayout方法纵向排列java代码

非常感谢您的提问。下面是用GridBagLayout方法纵向排列三个信息的java代码：

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

public class UserInterface extends JFrame {
    private JLabel label1, label2, label3;
    private JTextField textField1, textField2, textField3;
    private GridBagConstraints constraints;

    public UserInterface() {
        label1 = new JLabel("信息1:");
        label2 = new JLabel("信息2:");
        label3 = new JLabel("信息3:");
        textField1 = new JTextField(10);
        textField2 = new JTextField(10);
        textField3 = new JTextField(10);

        setLayout(new GridBagLayout());
        constraints = new GridBagConstraints();

        constraints.gridx = 0;
        constraints.gridy = 0;
        constraints.anchor = GridBagConstraints.WEST;
        add(label1, constraints);

        constraints.gridx = 0;
        constraints.gridy = 1;
        add(label2, constraints);

        constraints.gridx = 0;
        constraints.gridy = 2;
        add(label3, constraints);

        constraints.gridx = 1;
        constraints.gridy = 0;
        constraints.fill = GridBagConstraints.HORIZONTAL;
        add(textField1, constraints);

        constraints.gridx = 1;
        constraints.gridy = 1;
        add(textField2, constraints);

        constraints.gridx = 1;
        constraints.gridy = 2;
        add(textField3, constraints);

        pack();
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
    }

    public static void main(String[] args) {
        UserInterface userInterface = new UserInterface();
        userInterface.setVisible(true);
    }
}
