How do you save a page so you can view it without an internet connection?

Found this walkthrough…

java: view source, search for “applet code” (or ”.class”) and look for a .class file near it. save the source in your preferred directory. load the .class file from your browser address bar and save it to the same directory. run the copy of the source to play it.

flash: view source, search for “embed” (or ”.swf”) and look for a .swf file near it. load it from your browser address bar and save it. it will play in any web browser offline.
