Chapter 5, Problem 2PP
Add methods to the Person class from Self-Test Question 16 to perform the following tasks:
- Set the name attribute of a Person object.
- Set the age attribute of a Person object.
- Test whether two Person objects are equal (have the same name and age).
- Test whether two Person objects have the same name.
- Test whether two Person objects are the same age.
- Test whether one Person object is older than another.
- Test whether one Person object is younger than another.
Write a driver (test) program that demonstrates each method, with at least one true and one false case for each of the methods tested.

Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.
Modified Circle class and test file:
Add a new attribute for color (or any other new attribute)
Add get/set methods for this new instance variable, including data validation in set method (assuming background is black, i.e. circle color can't be black, reset to any non-black color if black is entered ).
Add a new constructor to pass the color attribute as an argument.
Add an instance method to display all properties of a Circle object.
Create 2 objects using different constructors in test file, with invalid data. Use this test java file
test java file:
class CircleTest{ public static void main(String[] args){ int num = 10; Circle c1 = new Circle(0.001); Circle c2 = new Circle("black", -9); c1.display(); c2.display(); c1.setRadius( -1); c1.setColor("black"); c1.display(); }}
Task
Write a class named Account to represent an account that you may find at a bank. Accounts have a balance and an annual interest rate. Include attributes in the Account class to reflect these.
Write getters for both attributes and a setter for only the annual interest rate. Think about how real bank accounts work, you change your balance by withdrawing and depositing money, not just by telling the banker how much you want to change it to.
Include a constructor with parameters used to assign values to both attributes.
Users should be able to withdraw money from an Account, deposit money into an Account, find monthly interest rate, and find monthy interest. Include methods for each of these actions. More details on them below.
withdraw method
This method simulates withdrawing money from the Account. It should not return a value and take the amount to withdraw as a parameter and reduce the balance by this amount.
deposit method
This method simulates depositing money into the Account.…

- Implement a Person class with the following attributes: Name: String Place of Birth: String Birthdate: Date Gender: String The constructor will receive the name and birthday date. The gender and the place of birth should be initialized as empty strings. Make the attributes private and create getter and setter methods. Write a __str__ method that prints the name and the age of the person (check the testcase for the format). To calculate the age just subtract the year of birth to the current year (don't worry about the day/month, it is not an objective of this exercise). A datetime object has a year attribute that is public. To get the current date, use: datetime.date.today() which also has a year attribute.arrow_forwardUsing JAVASCRIPT write an object prototype for a Person that has a name and age, has a printInfo method, and also has a method that increments the persons age by 1 each time the method is called.
