使用java的URL类解析URL地址

mport java.net.*;

import java.io.*;

public class ParseURL {

public static void main(String[] args)

throws Exception {

URL aURL = new URL("http://java.sun.com:80/docs/books/tutorial" + "/index.html?name=networking#DOWNLOADING");

System.out.println("protocol = " + aURL.getProtocol());

System.out.println("authority = " + aURL.getAuthority()); System.out.println("host = " + aURL.getHost());

System.out.println("port = " + aURL.getPort());

System.out.println("path = " + aURL.getPath());

System.out.println("query = " + aURL.getQuery());

System.out.println("filename = " + aURL.getFile());

System.out.println("ref = " + aURL.getRef());

}

}
