### Python Class and Method ExampleIn this example, we are defining a class `PersonInfo` with an instance method `inc_num_kids()` that increments the member data `num_kids`.#### Code Explanation:```pythonclass PersonInfo: def __init__(self): self.num_kids = 0 # FIXME: Write inc_num_kids(self) def inc_num_kids(self): self.num_kids += 1person1 = PersonInfo()print(f'Kids: {person1.num_kids}')person1.inc_num_kids()print(f'New baby, kids now: {person1.num_kids}')```- **Class Definition**: The class `PersonInfo` has an initializer method `__init__()` that sets `num_kids` to 0.- **Method `inc_num_kids()`**: This method, when called, will increment the `num_kids` attribute by 1.- **Object Creation**: `person1` is an instance of `PersonInfo`.- **Output Statements**: The program prints the number of kids before and after calling `inc_num_kids()`.#### Error Message:- **Test Error**: The program encountered an error, indicated by: ``` Exited with return code 1. Traceback (most recent call last): File "main.py", line 11, in person1.inc_num_kids() AttributeError: 'PersonInfo' object has no attribute 'inc_num_kids' ``` This indicates that there was an attempt to call a non-existing method `inc_num_kids()` on the `person1` object, which suggests that the method definition might not have been recognized due to outdated code or a missed update.#### Correction Notes:- Ensure the method `inc_num_kids` is correctly defined and attributed to the class `PersonInfo`.- Double-check that there are no syntax errors preventing the code from recognizing the method.Understanding these basic principles will help in addressing similar issues in object-oriented programming with Python.

Part 2: Sorting the WorkOrders via dates Another error that will still be showing is that there is not Comparable/compareTo() method setup on the WorkOrder class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the WorkOrder class. The compareTo() method will take a little work here. We are going to compare via the date of the work order. The dates of the WorkOrder are saved in a MM-DD-YYYY format. There is a dash '-' in between each part of the date. You will need to split both the current object's date and the date sent through the compareTo() parameters. You will have three things to compare against. You first need to check the year. If the years are the same value then you need to go another step to check the months, otherwise you compare them with less than or greater than and return the corresponding value. If you have to check the months it would be the same for years. If the months are the same you…
Write three static comparators for the any Point2D data type , one that compares points by their x coordinate, one that compares them by their y coordinate, and one that compares them by their distance from the origin. Write two non-static comparators for the Point2D data type, one that compares them by their distance to a specified point and one that compares them by their polar angle with respect to a specified point.

In C++ Create a new project named lab9_1 . You will need to implement a Course class. Here is its UML diagram: Course - department : string- course_num : string- section : int- num_students : int- is_full : bool + Course()+ Course(string, string, int, int)+ setDepartment(string) : void+ setNumber(string) : void+ setSection(int) : void+ setStudents(int) : void+ getDepartment() const : string+ getNumber() const : string+ getSection() const : int+ getStudents() const : int+ print() const : void Create a sample file to read from: CSS 2A 1111 35 Additional information: The Course class has two constructors. Make sure you have default values for your default constructor. Each course maxes out at 40 students. Therefore, you need to make sure that there aren’t more than 40 students in a Course. You can choose how you handle situations where more than 40 students are added. Additionally, you should automatically set is_full to false or true, based on the number of…
---for example, Data abstraction is a powerful concept in computer science that allows programmers to treat code as objects car objects, chair objects, people objects, etc. That way, programmers don't have to worry about how code is implemented they just have to know what it does. Data abstraction mimics how we think about the world. For example, when you want to drive a car, you don't need to know how the engine was built or what kind of material the tires are made of. You just have to know how to turn the wheel and press the gas pedal. An abstract data type consists of two types of functions: • Constructors: functions that build the abstract data type. • Selectors: functions that retrieve information from the data type. For example, say we have an abstract data type called city. This city object will hold the city's name, and its latitude and longitude. To create a city object, you'd use a constructor like city=make_city (name, lat, lon) To extract the information of a city object,…
Add the function min as an abstract function to the class arrayListType to return the smallest element of the list. Also, write the definition of the function min in the class unorderedArrayListType and write a program to test this function. I have 5 tabs: I have tried every solution I can think of with no luck. These are the guides: arrayListType.h arrayListTypeImp.cpp: main.cpp unorderedArraryListType.h unorderedArrayListTypeImp.cpp I am needing these in order to pass the assignment in Cengage Mindtap, please help with codes for each one if possible.

Write a base class (Person) that has the following data members: String name, long NID, int age. Your class (Person) should have setters and getters for all data members. Derive a class (Student) from class (Person). Class student should have the following private data members: Int id, double GPA, string major. Class (Student) should have setters and getters for its private data members. In your main function, create an object of class (Student) and set all of its data members.
