打开新标签页后如何删除之前的标签页？

Question

所以我正在制作一个小组项目，它是 Java 控制台 GUI。这是我的 Java 控制台 GUI 代码：

package com.nono.groupproject;

import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;
import javax.swing.ButtonGroup;

public class UserRegistrationGUIConsole extends JFrame {

    private JTextField nameField, addressField, phoneNumberField;
    private JRadioButton maleRadioButton, femaleRadioButton;
    private ButtonGroup sexButtonGroup;

    public UserRegistrationGUIConsole() {
        setTitle("User Registration");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel panel = new JPanel();
        panel.setLayout(new GridLayout(7, 2, 5, 5));
        panel.setBorder(BorderFactory.createEmptyBorder(20, 5, 5, 20));
        
        panel.add(new JLabel("Name:"));
        nameField = new JTextField();
        panel.add(nameField);

        panel.add(new JLabel("Address:"));
        addressField = new JTextField();
        panel.add(addressField);

        panel.add(new JLabel("Phone Number:"));
        phoneNumberField = new JTextField();
        panel.add(phoneNumberField);

        panel.add(new JLabel("Sex:"));
        maleRadioButton = new JRadioButton("Male");
        femaleRadioButton = new JRadioButton("Female");
        sexButtonGroup = new ButtonGroup();
        sexButtonGroup.add(maleRadioButton);
        sexButtonGroup.add(femaleRadioButton);
        panel.add(maleRadioButton);
        panel.add(femaleRadioButton);

        JButton registerButton = new JButton("Register");
        registerButton.addActionListener(e -> handleRegistration(e));

        panel.add(registerButton);

        setContentPane(panel);
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }

    private void handleRegistration(ActionEvent e) {
        // Your registration logic goes here
        throw new UnsupportedOperationException("Not supported yet.");
    }

    public static void main(String[] args) {
        new UserRegistrationGUIConsole();
    }
}

所以我输入了登录的用户名和密码，输入密码和用户名后，会出现一个新选项卡，但登录选项卡没有关闭。如何让它在打开新标签页后自动关闭？

Answer 1

我认为当登录过程完成时，你必须在

this.dispose()

中调用

handleRegistration(ActionEvent e)

方法
