a.java

这些是用java编写的小程序

package a;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class A {
	
	

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		
		try {
			ServerSocket s = new ServerSocket(8000);
			System.out.println("start......");
			Socket socket = s.accept();
			InputStream is = socket.getInputStream();
			FileOutputStream  fis = new FileOutputStream("d:\\a.bmp");
			int v ;
			while((v=is.read())!=-1)
			{
				fis.write(v);
			}
			fis.close();
			socket.close();
			System.out.println("end");
		} catch (IOException e) {
			// TODO 自动生成 catch 块
			e.printStackTrace();
		}
		// TODO 自动生成方法存根

	}
