public          


        

Answer 1

The accessor(getter) and mutator(setter) methods are generally used to provide encapsulation. As the instance variables are private they can only be accessed outside the class through these methods.

So In layman : the ability to make change in your implementation code without breaking the code of others who use your code is key benefit of encapsulation.
