Answer #1 
You wish to create a new class named MyNode.
what is the first line of the declaration of this class, assuming you want to create it as a publicly available class?
Answer:
--------
public class MyNode

what is meant by "mutator" when referring to a method?
Answer:
--------
since we can't directly access private variables of a class, we need special method to access them.
mutators(also known as setters) are used to set the value of a private field

what is meant by "accessor" when referring to a method?
Answer:
--------
since we can't directly access private variables of a class, we need special method to access them.
accessor(also known as getters) are used to get the value of a private field
