overriding is writing a special functionality to your subclass, Example if Vehicle is Superclass, Cycle is Subclass, then method drive can be overidden in Cycle class.

If you have parent class contains printDateMethod(), and you create a new class extended that parent class. So you end up with child class and parent class.

Now using printDateMethod() in the parent class output -> "12-31-2017".

But in the child class you want to change that output to -> "31-12-2017", therefore you can change printDateMethod() code inside your child class, but you need to write "@Override" above it, to notify the compiler (so he did not freak out, wondering why the child behave different than his parent).

that @Override called annotation, and there are more of them!

So overriding simply is replacing the parent code with new code in the child.
