Tcp实现客户端和服务器端的简单互访

import java.io.*;
import java.net.*;
public class TCPServer1 {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
ServerSocket ss=new ServerSocket(10005);
Socket s=ss.accept();

InputStream is=s.getInputStream();

byte[] b=new byte[1024];
int len=is.read(b);
if(len!=0){
System.out.println(new String(b,0,len));
}
OutputStream os=s.getOutputStream();
os.write("ni ye hao".getBytes());

s.close();
ss.close();
}
}

import java.io.*;
import java.net.*;
import java.util.Arrays;
public class TCPClient1 {
public static void main(String[] args) throws UnknownHostException, IOException {
// TODO Auto-generated method stub
Socket s=new Socket("127.0.0.1",10005);

OutputStream os=s.getOutputStream();
os.write("nihao".getBytes());

InputStream is=s.getInputStream();
byte[] b=new byte[is.available()];
is.read(b);
System.out.println(new String(b));//ni ye hao
System.out.println(Arrays.toString(b));//	[110, 105, 32, 121, 101, 32, 104, 97, 111]如果不用这个方法的话打印出来的将会是地址值
