**客户端**

package com.n3;
    
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.OutputStream;
    import java.net.Socket;
    import java.net.UnknownHostException;
    
    import com.sun.org.apache.bcel.internal.generic.NEW;
    
    public class Client {
        
    
    	public static void main(String[] args) throws UnknownHostException, IOException {
        
    		// TODO Auto-generated method stub
    		
    		while(true) {
        
    			//创建发送的socket
    			Socket socket=new Socket("192.168.110.96",9999);
    			//获取写出的
    			OutputStream oStream=socket.getOutputStream();
    			//写内容
    			oStream.write("我来了".getBytes());
    			InputStream inputStream=socket.getInputStream();
    			byte[] b=new byte[1024];
    			inputStream.read(b);
    			System.out.println(new String(b));
    		}
    
    	}
    
    }

**服务器端**

package com.n3;
    
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.OutputStream;
    import java.net.ServerSocket;
    import java.net.Socket;
    
    public class Server {
        
    
    	public static void main(String[] args) throws IOException {
        
    		// TODO Auto-generated method stub
    		//创建一个ServerSocket监听一个端口
    		ServerSocket ss=new ServerSocket(9999);
    		while(true) {
        
    			//接收数据 阻塞
    			Socket socket=ss.accept();
    			//获取到输入流
    			InputStream inputStream=socket.getInputStream();
    			//获取流中的数据
    			byte[] b=new byte[1024];
    			inputStream.read(b);
    			String string=new String(b);
    			System.out.println(string);
    			OutputStream oStream=socket.getOutputStream();
    			oStream.write("收到了".getBytes());
    		}
    	}
    
    }
