想了解Java模拟qq软件的详细过程的相关内容吗,冷丁_在本文为您仔细讲解Java 模拟 qq的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Java,模拟,qq,Java,qq,界面模拟,下面大家一起来学习吧。

**之前在封装代码后出现了问题,按照最初的写法,在登陆完毕后弹出聊天界面后会卡死,原因是当时登陆界面和聊天界面都是使用的主线程,我的代码没有写其他线程,无法多线程运行,因此在弹出聊天界面时线程不够用了,就卡在了监听线程里,因为在监听线程中再有新的监听就会被卡住
在宇哥的指点下,将启动服务器和客户端的部分改为线程,就解决了此问题。改善后的代码简练和清晰了很多,更方便大家参考,代码如下:
**

登陆界面的实现

登陆界面主要使用了JFrame,以及相关的一些组件,并且在界面中加上监听
登陆界面效果图

在这里插入图片描述

登陆界面代码Login类

package com.lding.net;

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

/**

public class Login{
    JTextField jTextField;


    public static void main(String[] args){
        Login login = new Login ();
        login.showUI ("kk");
    }

    public void showUI(String str){
        JFrame jf = new JFrame ();
        jf.setTitle ("❤️DDqq登陆界面❤️");
        jf.setSize (500, 400);
        jf.setDefaultCloseOperation (3);
        jf.setLocationRelativeTo (null);
        jf.setResizable (false);
        FlowLayout fl = new FlowLayout (FlowLayout.CENTER, 5, 5);
        jf.setLayout (fl);
        Dimension dim1 = new Dimension (500, 200);//图片大小
        Dimension dim2 = new Dimension (100, 50);//标签大小
        Dimension dim3 = new Dimension (300, 30);//输入框大小
        Dimension dim4 = new Dimension (100, 40);//按钮大小

        ImageIcon icon = new ImageIcon ("source/Login1.jpg");
        JLabel labimg = new JLabel (icon);
        labimg.setPreferredSize (dim1);
        jf.add (labimg);

        JLabel labuser = new JLabel ();
        labuser.setText ("user:");
        labuser.setPreferredSize (dim2);
        jf.add (labuser);
        JTextField textuser = new JTextField ();
        textuser.setPreferredSize (dim3);
        jf.add (textuser);

        JLabel labpassword = new JLabel ();
        labpassword.setText ("password:");
        labpassword.setPreferredSize (dim2);
        jf.add (labpassword);

        JPasswordField textPassword = new JPasswordField ();
        textPassword.setPreferredSize (dim3);
        jf.add (textPassword);

        JButton button = new JButton ();
        button.setBorder (BorderFactory.createRaisedBevelBorder ());
        button.setText ("login");
        button.setPreferredSize (dim4);
        jf.add (button);
        jf.setVisible (true);

        LoginListener ll = new LoginListener(textuser,textPassword, jf);
        button.addActionListener (ll);
        this.jTextField=ll.jTextField;

    }
}


login的监听类 LoginListener

package com.lding.net;

import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

/**
 * @program: Chat
 * @description:
 * @author: 王丁
 * @date: 2021-09-26 08:59
 **/
public class LoginListener implements ActionListener {
    JTextField jTextField;
    JPasswordField jPasswordField;
    JFrame jf ;
    LoginListener( JTextField jTextField,JPasswordField jPasswordField,JFrame jf){
        this.jf=jf;
        this.jTextField = jTextField;
        this.jPasswordField = jPasswordField;
    }
    @Override
    public void actionPerformed(ActionEvent e){
        if(jTextField.getText().equals("Alice")&&String.valueOf(jPasswordField.getPassword()).equals("1234")){
            System.out.println ("服务端登录!!");
            String name =jTextField.getText();
            new Server(name).start();
            jf.dispose();

        }else if(jTextField.getText().equals("Lding")&&String.valueOf(jPasswordField.getPassword()).equals("1234")){

            String name =jTextField.getText();
            System.out.println ("客户端登录!!");
            new Client(name).start();
            jf.dispose();
        }


    }
}

在登陆完毕后,需要跳转到聊天界面,这里采用的方法是通过一个flag标志来判断是否登陆完毕,当登陆完毕后,会创建新的聊天界面,并且登陆页面会被关闭
依然是双端通信,假定一端为客户端,一端为服务端,其实两端都可为用户。

聊天界面运行图

先登陆Alice的账号 密码为123456

在这里插入图片描述

登陆成功后显示ok,并等待连接

在这里插入图片描述

再登陆冷丁的账号,密码为123456

在这里插入图片描述

当lding账号登陆成功后完成连接,这时候会弹出两个新的JFram窗口,为聊天见面

在这里插入图片描述

随后可以发送消息,消息可以实时显示时间,并显示用户名
一方发送的消息会在另一方的窗口上实时显示出来

在这里插入图片描述
