一、url类 import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.MalformedURLException; import java.net.URL;
public class StreamTest4 {

try {
URL url=new URL("https://www.baidu.com");//windows系统，直接baidu后，直接右键-属性-复制url地址就可以
//但是mac系统，就比较无语
inStream=url.openStream();
//查看 inStream指向对象的类型是什么？
System.out.println(inStream.getClass());
outStream=new FileOutputStream("/Users/hanzhao/Desktop/1.html");
//windows系统，就随便保存为“d:\\1.png”就好，但是mac系统试了试就只能保存为.html格式
IOUtils.copy(inStream, outStream);
System.out.println("下载成功");
} catch (MalformedURLException e) {
