Best way to create the game window?

Newbie & Debugging Questions
#1

I’ve seen a lot of different implementations. For example, this(http://www.java-gaming.org/?action=pastebin&id=143) one creates a JFrame and a Canvas (i don’t know what for) but this (http://zetcode.com/tutorials/javagamestutorial/basics/) one has the main class extend JFrame and then uses JPanels to place all the content on. Are there pros and cons for each method of doing so? Or is one simply better than the other?
