Create a class called Staff that has the following attributes: Staff String - FirstName String - LastName String - Department String - Title Integer - UIN Staff() Staff(FirstName, LastName, Department, Title, UIN) getFirstName() - String setFirstName(String) - void getLastName() - String setLastName(String) - void getDepartment() - String setDepartment(String) - void getTitle() - String setTitle(String) - void getUIN() - Integer setUIN(Integer) - void toString() - String compareTo(Staff) - Integer equals(Staff) - Boolean PreviousNext
Create a class: "Palindrome" with private data members: upper limit (int), lower limit (int) and parameterized constructor, which initializes the values of both data members. Apart from initialization, this constructor also displays the count of palindrome numbers from upper_limit to lower_limit. [Example: upper limit:50, lower_limit:10, count of palindrome numbers is: 4(11 , 22, 33 and 44), also make sure the value of upper_limit should be greater than lower limit].

Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Planet code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information for each planet: Name, distance from sun, radius, and mass. section 10.4

• RectangleTest class: o Perform the following actions in the main method: • Create an object named r1 of the Rectangle class using the default constructor. • Using the set methods, initialize rl to have width 3.0 and length 5.2. • Use the printDimensions method to output all the data (width & length) related to r1. • Create another object named r2 of the Rectangle class with width 2.6 and length 5.4 using the overloaded constructor. • Print out r2 (width & length) using the get methods. • Print out the area and the perimeter of r1 using the calculateArea and calculatePerimeter methods. • Print out the area and the perimeter of r2 using the calculateArea and calculatePerimeter methods.
