            socket = null;
        }

}

客户端的代码：

package bhz.bio;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

public class Client {

    final static String ADDRESS = "127.0.0.1";
    final static int PORT = 8765;
    
    public static void main(String[] args) {
        
        Socket socket = null;
        BufferedReader in = null;
        PrintWriter out = null;
        
        try {
            socket = new Socket(ADDRESS, PORT);
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out = new PrintWriter(socket.getOutputStream(), true);
            
            //向服务器端发送数据
            out.println("接收到客户端的请求数据...");
            out.println("接收到客户端的请求数据1111...");
            String response = in.readLine();
            System.out.println("Client: " + response);
            
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if(in != null){
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if(out != null){
                try {
                    out.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            if(socket != null){
                try {
                    socket.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            socket = null;
        }
    }
}

我们来对上面的功能进行总结：
