例、

服务端：

package tcp;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintWriter;import java.net.ServerSocket;import java.net.Socket;public class Server {    /**     * Socket服务端     */    public static void main(String[] args) {        try {            ServerSocket serverSocket=new ServerSocket(8888);            System.out.println("服务端已启动，等待客户端连接..");            Socket socket=serverSocket.accept();//侦听并接受到此套接字的连接,返回一个Socket对象                                    //根据输入输出流和客户端连接            InputStream inputStream=socket.getInputStream();//得到一个输入流，接收客户端传递的信息            InputStreamReader inputStreamReader=new InputStreamReader(inputStream);//提高效率，将自己字节流转为字符流            BufferedReader bufferedReader=new BufferedReader(inputStreamReader);//加入缓冲区            String temp=null;            String info="";            while((temp=bufferedReader.readLine())!=null){                info+=temp;                System.out.println("已接收到客户端连接");                System.out.println("服务端接收到客户端信息："+info+",当前客户端ip为："+socket.getInetAddress().getHostAddress());            }                        OutputStream outputStream=socket.getOutputStream();//获取一个输出流，向服务端发送信息            PrintWriter printWriter=new PrintWriter(outputStream);//将输出流包装成打印流            printWriter.print("你好，服务端已接收到您的信息");            printWriter.flush();            socket.shutdownOutput();//关闭输出流                                                //关闭相对应的资源            printWriter.close();            outputStream.close();            bufferedReader.close();            inputStream.close();            socket.close();                    } catch (IOException e) {            e.printStackTrace();        }    }}

客户端：

package tcp;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintWriter;import java.net.Socket;import java.net.UnknownHostException;public class Client {    /**     * Socket客户端     */    public static void main(String[] args) {        try {            //创建Socket对象            Socket socket=new Socket("localhost",8888);                        //根据输入输出流和服务端连接            OutputStream outputStream=socket.getOutputStream();//获取一个输出流，向服务端发送信息            PrintWriter printWriter=new PrintWriter(outputStream);//将输出流包装成打印流            printWriter.print("服务端你好，我是Balla_兔子");            printWriter.flush();            socket.shutdownOutput();//关闭输出流                        InputStream inputStream=socket.getInputStream();//获取一个输入流，接收服务端的信息            InputStreamReader inputStreamReader=new InputStreamReader(inputStream);//包装成字符流，提高效率            BufferedReader bufferedReader=new BufferedReader(inputStreamReader);//缓冲区            String info="";            String temp=null;//临时变量            while((temp=bufferedReader.readLine())!=null){                info+=temp;                System.out.println("客户端接收服务端发送信息："+info);            }                        //关闭相对应的资源            bufferedReader.close();            inputStream.close();            printWriter.close();            outputStream.close();            socket.close();        } catch (UnknownHostException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }    }}
