-Watch the LinkedIn Learning course: Programming Foundations: Object-Oriented Design with Olivia Stone and Barron Stone
-Watch this LinkedIn Learning section: Section 1 – UML Basics from the course: iOS Development: Architecture with KarolyNyisztor
-Watch the LinkedIn Learning section: Diagramming with UML from the Course Java Essential Training for Students with Peggy Fisher

Define Classes and Create Objects by reading the following:
-Creating Objects
-Data Access Object
a) Define classes for objects
b) Define object state and behavior
c) Define constructors
d) Instantiate objects
e) Access objects using reference variables
f) Access objects data and methods
g) Reference objects data fields
Learn how to implement the class by reading the following:
Implementing an Interface
a) Define class accessibility and modifier
b) Explore the main() method
c) Define the default constructor and private data
d) Define instances and static variables
e) Define instance and static methods
f) Define Getter and setter methods
g) Use this keyword for referencing the calling object itself
Research the three essential features of objects:
• state
• behavior
• identity
Define the terms and describe how they relate to one another. Cite at least two sources using APA from the library database.
PART 2
2) Work individually to implement the class defined and discussed in (1), compile, and run the class using NetBeans. Students then work together to resolve errors (if any).
3) Work individually or in the group to add two instance methods to the Circle class that compute the area of the circle and the circumference of the circle.
Assessment:
Students work individually to create the Square class using both UML and Java notation and add an instance method to calculate the perimeter of the square. The student(s) then implement, compile and run the class in NetBeans. Submit the results below in a Word or PDF document.
