An object of the xClass may be created by providing a value for all 3 of these states and also by providing only x & y. 

The yClass has 2 int states, a & b. 

An object of the yClass may be created by providing a value for a, or values for both a & b. 

The zClass is a type of yClass and has 1 int state called c. 

An object of the zClass may be created with or without supplying a value for c.

Blog Task - The Constructor

Wow this turned out to be a big class.

I viewed this Player Account and treated it in a way similar to World of Warcraft.

Each player has a Player Account that must be set up before you can create avatars to play.

Each Player Account has required parameters and also have data types that are themselves class objects.

The DOB class has 3 states, dd, mm, and yyyy.

The Avatar class has 4 states, name, race, sex and class.

Blog Task - Encapsulation and Visibility

Accessors and Mutators allow exterior objects read or modify access to an objects public states and behaviours.

In UML diagrams each Accessor and Mutator is preceeded by a plus sign, ( + ), which identifies that the object state or behaviour is public.

In UML diagrams a minus sign, ( - ), denotes a state or behaviour is private, and as such is not acceable by on outside object.


What is an Accessor?

An Accessor allows outside objects to read the state or behaviour of an object. 
Accessors are also known as Getters.


What is a Mutator?

A Mutator allows outside objects to modify the state or behaviour of an object.
Accessors are also known as Setters.

The quiver has a maximum arrow capacity and weight 

It can also only be equipped by an Archer

It increases the Archer accuracy skill
