package com.lippeng.helloworld;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.URL;public class HelloWorld {    public static void main(String[] args) throws IOException {String path = "http://172.21.153.58:9090/TFTP/run.bat";URL url = new URL(path);InputStream inputStream = url.openStream();OutputStream outputStream = new FileOutputStream("run.bat");byte[] b = new byte[1];int count = inputStream.read(b);while (count != -1) {    outputStream.write(b, 0, count);    count = inputStream.read(b);}inputStream.close();outputStream.close();    }}
