以下实例演示了如何使用 net.URL 类的 url.getProtocol() ,url.getFile() 等方法来解析 URL 地址：
Main.java 文件
import java.net.URL;
public class Main {
public static void main(String[] args)
throws Exception {
URL url = new URL("http://www.codercto.com/html/html-tutorial.html");
System.out.println("URL 是 " + url.toString());
System.out.println("协议是 " + url.getProtocol());
System.out.println("文件名是 " + url.getFile());
System.out.println("主机是 " + url.getHost());
System.out.println("路径是 " + url.getPath());
System.out.println("端口号是 " + url.getPort());
System.out.println("默认端口号是 "
+ url.getDefaultPort());
}
}
以上代码运行输出结果为：
URL 是 http://www.codercto.com/html/html-tutorial.html 协议是 http 文件名是 /html/html-tutorial.html 主机是 www.codercto.com 路径是 /html/html-tutorial.html 端口号是 -1 默认端口号是 80
