1. Provide answers to the following Check Point Questions from our textbook (5 points):
a. How do you define a class? How do you define a class in Eclipse?
b. How do you declare an object's reference variable (Hint: object's reference variable
is the name of that object)?
c. How do you create an object?
d. What are the differences between constructors and regular methods?
e. Explain why we need classes and objects in Java programming.
2. Write the Account class. The UML diagram of the class is represented below (10 points):
Account
id: int = 0
- balance: double = 0
- annualInterestRate: double = 0.02
- dateCreated: java.util.Date
+ Account()

THIS IS NOT A GRADING ASSIGNMENT:
Please only do lab 2.2 (bottom part of the first picture)
For that Lab 2.2 do:
*Part 1 (do the CODE, that's super important I need it)
*Part 2
*Part 3
I also attached Section 2.5.2 which is part of the step 1 so you can read what is it about.
Thank you!
