简单的聊天时范例(客户端)-优快云博客

本文介绍了一个简单的聊天室程序实现，包括服务器端和客户端代码。服务器端监听8888端口，接收客户端发送的消息并打印；客户端连接到服务器，接收服务器发送的消息并显示。双方通过两个独立线程分别处理消息接收和发送。

package j2se.core.net.chat;

import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

/**

public class Server {

public static void main(String[] args) throws IOException {
ServerSocket server = new ServerSocket(8888);
while (true) {
final Socket socket = server.accept();
Thread t1 = new Thread() {
@Override
public void run() {
DataInputStream input;
try {
input = new DataInputStream(socket.getInputStream());
while (true) {
String s = input.readUTF();
System.out.println("客户端说:" + s);
}
} catch (IOException e) {
e.printStackTrace();
}
}
};
t1.start();

Thread t2 = new Thread() {
@Override
public void run() {
BufferedReader br = new BufferedReader(
new InputStreamReader(System.in));
try {
DataOutputStream out = new DataOutputStream(
socket.getOutputStream());
while (true) {
String s = br.readLine();
out.writeUTF(s);
}
} catch (IOException e) {
e.printStackTrace();
}
}
};
t2.start();
}
}

}
