• Assignment A6. Finding links on webpages. Due on the CMS 2May 2004 by 11:59. doc file     pdf file.
  TagIterator      LinkIterator      Set
  This is a link to the first page of a test web site for this assignment. It has three pages. Our testing program will be testing your program with some more elaborate pages. There are here only to get you started. The URL for the first page is:
       http://www.cs.cornell.edu/courses/cs211/2004sp/testA6/page1.html

  Here is a zip file with html pages and images. Use it to test: testa6.zip

  Download the zip file and put it in some directory and unzip it. You can then test on your machine without having to be on the internet. However, you have to know whaaaaaat url to use for the first webpage, index.html. You can determine this by trying to load a local file into your browser --a navigation window should appear, and you navigate to the directory and select the file. Then, the file will be loaded into your browser and the URL will appear in the url field. I can't tell you what to use for a URL; it differs from operating system to operating system.

  When dealing with files on your computer, you maa have trouble with the URLs. Suppose you nwant the following for the URLs s1 and s2 (e.g. on a Mac):
  
  
  s1: file:///Volumes/work17/CS211/testa6/index.html
  s2: file:///Volumes/work17/CS211/testa6

  Then do this:
  
  String s1= "file:///Volumes/work17/CS211/testa6/index.html";
  String s2= "file:///Volumes/work17/CS211/testa6";
  URL us1= new URL(us1);
  URL us2= new URL(us2);
  s1= us1.toString();
  s2= us2.toString();
  
  On the Macintosh (Panther operating system), the final value of s1 looks slightly different from the initiall value of s1.
