Expert answer:Milestone Three: Programmer-Defined Class

Solved by verified expert:For this Third Milestone, you will finish development of your MyClone class and create another class of your choice.In Module Two, you started development of the MyClone class. You will continue to develop the MyClone class by adding accessor methods, mutator methoda, and an introduction() method. The introduction() method will introduce yourself to the virtual world by displaying a greeting, your first and last name, and anything else you would want to say. You will also create another class of your choice. Your programmer-defined class should have at a minimum two instance variables and one method. The instance variables and method should be representative of the data and behavior that objects of this class will have. You will demonstrate your understanding of encapsulation by declaring the instance varibales as private and by creating accessors and mutatora for each instance variable. You should have at least one constructor created that initializes all instance variables. Document your code. Submit your .class and .java files as one zipped folder. For additional details, please refer to the Milestone Three Rubric document and the Final Project Guidelines and Rubric document in the Assignment Guidelines and Rubrics section of the course.Guideline is attached

Milestone Three: Programmer-Defined Class Guidelines and Rubric
You created the initial version of your MyClone class in Milestone One and Java code that created an Array of String messages in Milestone Two. In this milestone,
due in Module Seven, you will finish your MyClone class and create another class of your choice.
The following critical elements will be addressed in this submission:
1. MyClone accessors and mutators: You will demonstrate your understanding of encapsulation by creating accessor and mutator methods for all instance
variables of the MyClone class.
2. MyClone constructor: You should have at least one constructor created that initializes all instance variables.
3. MyClone method introduction(): Create an introduction() method for your MyClone class. The introduction() method will introduce you to the virtual
world by displaying a greeting, your first and last name, and anything else you would want to say.

-lastName

4. Create an additional class: Create a class of your choice. Your programmer-defined class will have at a minimum two (2) instance variables and one (1)
method. You will demonstrate your understanding of encapsulation by declaring the instance variables as private and by creating accessors and mutators
for each instance variable.
5. Constructor: You will implement at least one constructor that initializes all instance variables. Document your code.

MyClone class includes
accessors and mutators for all
attributes.
(9-10)
Meets “Proficient” criteria and
more than one overloaded
constructor is provided.
(8)
MyClone class includes at least
one constructor that sets all
instance variables to an initial
value.
(8)
Method correctly displays a
greeting, the full name of the
clone, and an introduction
statement for the virtual world
(9-10)
Meets “Proficient” criteria
substantiated with formatted
printing used to display the
introduction; message
displayed is aesthetically
pleasing; introduction() method
uses accessor methods to get
the current value of the first
name and last name attributes

instance variables with
associated accessors and
mutators and 1 successful
method
(36-40)
(32-35)
Needs Improvement
MyClone class includes some
accessors, but the accessors do
not return the correct value of
the instance variables. MyClone
class includes some mutators,
but the mutators do not
correctly change the instance
variable.
(7)
MyClone class includes a
constructor but the constructor
does not set all instance
variables to an initial value.
(7)
Method displays a greeting, the
full name of the clone, and an
introduction statement for the
virtual world, but not correctly
Not Evident
MyClone class does not include
accessors and mutators, or the
accessors and mutators do not
compile.

instance variables with
associated accessors and
mutators and 1 method, but the
method is not successful or the
