Create a Java Project (with a class and a test class) to represent some real-world entity such as a technology item (TV, Fan etc), an animal, a person, a vehicle, etc. In our class, we have already seen example classes such as Circle, Student, Rectangle, TV etc. The class will: a) Create a total of 5 member variables for the class by selecting the appropriate data types for each field. For example, a class to represent a lamp might include color, price, height, numBulbs, battery Operated. Each of these 5 variables needs a data type. b) Include at least three different constructor methods, including the default constructor (no argument constructor), so totally three constructors. c) Create a member function showValues() to display the values of an object in a formatted manner. The Java test class (with a main method) will: a) Instantiate at least three objects (using each of the constructors at least once) with your program. b) Store the data from the individual objects into an array. c) Utilize the showValues() method to display the content of an object created. Note: 1) Draw the UML diagram for the class and then implement the class. Draw object diagrams wherever possible to show the state of the objects created 2) Generate output samples demonstrating all of your member functions showing their functionality (i.e. inputting values, outputting values (displaying them), performing calculations, etc.). Include the below in your project report: 1. The UML diagram of the class. 2. The class and test class 3. Screenshots of output generated from the application.

Complete the question above.
Transcribed Image Text:Create a Java Project (with a class and a test class) to represent some real-world entity such as a
technology item (TV, Fan etc), an animal, a person, a vehicle, etc. In our class, we have already
seen example classes such as Circle, Student, Rectangle, TV etc.
The class will:
a) Create a total of 5 member variables for the class by selecting the appropriate data types
for each field. For example, a class to represent a lamp might include color, price, height,
numBulbs, batteryOperated. Each of these 5 variables needs a data type.
b) Include at least three different constructor methods, including the default constructor
(no argument constructor), so totally three constructors.
c) Create a member function showValues() to display the values of an object in a formatted
manner.
The Java test class (with a main method) will:
a) Instantiate at least three objects (using each of the constructors at least once) with your
program.
b) Store the data from the individual objects into an array.
c) Utilize the showValues() method to display the content of an object created.
Note:
1) Draw the UML diagram for the class and then implement the class. Draw object diagrams
wherever possible to show the state of the objects created
2) Generate output samples demonstrating all of your member functions showing their
functionality (i.e. inputting values, outputting values (displaying them), performing
calculations, etc.).
Include the below in your project report:
1. The UML diagram of the class.
2. The class and test class
3. Screenshots of output generated from the application.
