Majid,

Generally
Classes and interfaces can contain methods. Sometimes you don't want to use the method the way it is written and then you override the method.
When you implement an interface, you are agreeing to a "contract" that says you must implement the methods in the interface. Very often these methods are just a template. Then you override them in your code and give them your own functionality
.
Specifically
The Blank activity assumes you want to use the menu capability  of the Action Bar.
Therefore it creates the mandatory methods that you  need to override.
However, the purpose of the tutorial is to  teach a concept that does not require the menus, so you are instructed to delete the overrides since the detract from the concept being presented.

Jump to tutorial # 33 if you want to see the menu overrides implemented.
