Socket示例代码

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;

public class DLLSocket {

	public static void main(String[] args) {
		String ip = "10.180.192.18";
		int port = 4000;
		try {
			Socket socket = new Socket(ip, port);
			socket.setSoTimeout(5539900);
			java.io.OutputStream out = socket.getOutputStream();

			byte[] date = "hello world".getBytes();
			out.write(date);
			out.flush();
			socket.shutdownOutput();

//			byte[] buffer = new byte[1024];
//			int len = -1;
//			java.io.FileOutputStream fout = new java.io.FileOutputStream("d:/response.xml");
//			java.io.ByteArrayOutputStream bout = new java.io.ByteArrayOutputStream();
//			java.io.InputStream in = socket.getInputStream();
//
//			while ((len = in.read(buffer, 0, buffer.length)) > 0) {

//			}
//			in.close();
//			bout.flush();
//			bout.close();
