Java练手小程序——QQ聊天

1.思路图

       

2.主要功能

        实现一对一聊天
实现多对多聊天
好友上线自动刷新功能

3.知识点

      界面布局：一是流布局，二是卡片布局（现在应该都不用了）
 socket通信之对象流objectinput/outputStream

         将线程里面的信息显示到界面上

4.项目代码

       4.1服务端

          


            common下有三个类：

            Message.java

            package com.qq.common;

public class Message implements java.io.Serializable{

private String mesType;

private String sender;
private String getter;
private String con;
private String sendTime;

public String getSender() {

}

public void setSender(String sender) {

}

public String getGetter() {
return getter;
}

public void setGetter(String getter) {
this.getter = getter;
}

public String getCon() {
return con;
}

public void setCon(String con) {
this.con = con;
}

public String getSendTime() {
return sendTime;
}

public void setSendTime(String sendTime) {
this.sendTime = sendTime;
}

public String getMesType() {
return mesType;
}

public void setMesType(String mesType) {

}
}
            
            接口MessageType.java
