Java小项目之：聊天系统
今天给大家带来的java练手小项目是一个简单的聊天室，界面简单，操作不难。
分为注册系统，登录系统和聊天系统三部分，很适合java小白练手。
完整的源码和素材请关注并私信我获取！
界面展示：
代码展示：
package chatRoom2;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.Socket;
public class Client {
/**

try {
socket = new Socket("127.0.0.1", 8000);
new ClientWriterThread(socket).start();
new ClientReaderThread(socket).start();
} catch (Exception e) {
e.printStackTrace();
