Please make sure to add a deafult constructor to the program and create a class diagram.

Instructions: Convert your V3 object class from the Default Constructors assignment to V8 mplementation and client classes and instantiate multiple objects 1. Create a 05.08 Assignment project in the Modos Assignments folder 2. Read the instructions carefully before you attempt the assignment 3. Before you begin coding, use a word processor to create a class diagram 4. In the 05.08 Assignment project, create a V8 class for your object and a VB Toster class Use Planets as a model 5. Copy any part of your V3 object class you'd like to reuse and paste it into the appropriate claus choll you just created Change any statements that mention va love 6 Comple the project to make sure no errors were introduced and run the program to venly that it still works Fix any errors that show up before moving on to the next stop 7. In the object implementation class, declare private instance verlables, define a baded construcior, and iritalize the instance variables Deline at least come overloaded method Ad any methods to your object you'd like 8. In the chant class, instantiate at igast three instances of your Vey object. Invoke the necessary merods to calculate or manipuinate data for the objects 9. Print the results in a user friendly format. (Hint: use the tescape character) 10. Be sure to document each section of the code Expected Output: When the program uns correctly, the output will resemble the following screenshot Yout output will show rest for your objects Buah Terminal Winde 5.00 CS Option Student Grade 1 Grade 2 Average 07.5 John Alisa Jessica 85 90 92 90 92 84 91.0 88.0
