Socket(1)--简单例子

代码例子：

package com.test;

import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

/**
 * 服务端
 * 
 * @author yale
 * 
 */
public class TcpServer
{
	public static void main(String[] args) throws Exception
	{
		ServerSocket ss = new ServerSocket(5000);

		Socket socket = ss.accept();//等待接受   阻塞

		OutputStream os = socket.getOutputStream();

		os.write("hello client ".getBytes());

		InputStream in = socket.getInputStream();

		byte[] buffer = new byte[1024];

		int length = 0;

		while (-1 != (length = in.read(buffer, 0, buffer.length)))
		{
			String str = new String(buffer, 0, length);
			System.out.println(str);
		}
		os.close();
		in.close();
		socket.close();

	}
}

package com.test;

import java.io.InputStream;
import java.io.OutputStream;
import java.net.Socket;
/**

public class TcpClient
{
	public static void main(String[] args) throws Exception
	{
		Socket socket =new Socket("127.0.0.1",5000);
		
		OutputStream os = socket.getOutputStream();
		
		os.write("hello server ".getBytes());
		
		InputStream in = socket.getInputStream();

		byte[] buffer = new byte[1024];

		int length = 0;

		while (-1 != (length = in.read(buffer, 0, buffer.length)))
		{
			String str = new String(buffer, 0, length);
			System.out.println(str);
		}
		os.close();
		in.close();
		socket.close();
