1.基于连接的Java网络编程
实现了基于TCP的Java Socket编程，功能很简单：客户端向服务器端输出一名话"connect"，服务器端接收输出到控制台并向客户端输出一名话"Hello",客户端接收并输出。1.服务器端
package javase.net.socket;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.ServerSocket;import java.net.Socket;public class TCPServer { public static void main(String[] args) { try { ServerSocket serverSocket = new ServerSocket(8888); Socket socket = serverSocket.accept(); // 读取客户端数据 InputStream info = socket.getInputStream(); DataInputStream dis = new DataInputStream(info); System.out.println(dis.readUTF()); // 向客户端输出数据 OutputStream os = socket.getOutputStream(); DataOutputStream dos = new DataOutputStream(os); dos.writeUTF("Hello!"); dos.flush(); } catch (IOException e) { e.printStackTrace(); } }}
2.客户端：
package javase.net.socket;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.Socket;import java.net.UnknownHostException;public class TCPClient {public static void main(String[] args) {try {Socket socket = new Socket("192.168.1.123", 8888);// 向服务器端发送数据OutputStream os =socket.getOutputStream();DataOutputStream bos = new DataOutputStream(os);bos.writeUTF("Connect");bos.flush();// 接收服务器端数据InputStream is = socket.getInputStream();DataInputStream dis = new DataInputStream(is);System.out.println(dis.readUTF());} catch (UnknownHostException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}
