The difference between "extend" and " implements' is :
A class can extend the functionality of the super class,
Here the super class, will already have some methods defined and
functionality implemented witin them,
so in your sub class you can add some more function.
A class has to implement the functionality of the super class
Here the super class will have only the signature of the method but
does not define how the class behaves, it is felt to the sub class
which implements this class.
Hope you understood, having this knowledge you can apply it to your example.
