Steps 1. Implement a class representing a student. A student needs to hold the following attributes: i. First name ii. Last name iii. Credit points. Raise exception if the number is negative iv. Credit hours. Raise an exception if the number is negative 2. Add a function print_info to the Student Class to print the student's information. Additionally, add setters and getters functions to set and get all the attributes 3. Implement a class StudentGrad that inherits from the Student Class. In needs to add those extra attributes: i. bachelor degree 4. Override print_info function from the parent class to call the print_info from the parent and then print the bachelor degree. Additionally, add a getter and a setter function to set the bachelor degree attribute. 5. Implement test_student in the main to test the Student and GradStudent classes 6. Implement the Queue class. You can use the Queue class implementation that is posted in zybook. 7. Implemente the test_queue function to test that the Queue class is working properly 8. Implement function program to run the all the needed steps

5. Declare a class called coordinate. This is to represent 3 dimensional Cartesian coordinates (x, y and z).Define the following methods cumulatively in Java cumulatively:a. Constructorb. Display, to print values of membersc. Add_coordinates, to add three such coordinate objects to produce a resultant coordinate object.Generate and handle exceptions if x, y and z coordinate of the result are zero.d. Main, to show use of the above methods.

Written in Python with docstring please if applicable Thank you

PLZ help with the following: True/False In java it is possible to throw an exception, catch it, then re-throw that same exception if it is desired GUIs are windowing interfaces that handle user input and output. An interface can contain defined constants as well as method headings or instead of method headings. When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. Can you have a static method in a nonstatic inner class?

g) Make a class Class (as in a class of students, not a class as in a class of objects) that stores several Student objects. Store a list of students in an attribute called students. The initializer method should initialize the class as an empty class (no students). Implement a method add_student() that takes an object of class Student and adds it to class. Implement method pass_rate() that determines the fraction of students that pass the class (have a grade of >= 6). python code!!

array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.
