    {      

        URL a=new URL("http://www.google.com?hello%2osachin%20");

        URL a1=new URL("http://www.google.com/adsense");

        String str=a.getProtocol();

        System.out.println("The Protocol is: "+str);

        String str1=a.getHost();

        System.out.println("The Host is: "+str1);

        String str2=a1.getFile();

        System.out.println("The File is: "+str2);

        String str3=a.getQuery();

        System.out.println("The Query is: "+str3);

        String str4=a1.getPath();

        System.out.println("The Path is: "+str4);

        String str5=a1.getRef();

        System.out.println("The Reference is: "+str5);

        int n=a.getPort();

        System.out.println("The Port Number is: "+n);

    }

    catch(Exception e)

    {

    System.out.println(e);}}
