1. Define a Python class called `PersonInfo` to represent person-related information.2. Inside the `PersonInfo` class: a. Define the `__init__` constructor method: - Initialize an instance variable `num_kids` to 0, representing the number of kids for a person. b. Define the `inc_num_kids()` instance method: - Inside this method, increment the `num_kids` instance variable by 1. This method is used to simulate the addition of a new baby.3. Create an instance of the `PersonInfo` class and assign it to a variable, such as `person1`.4. Print the initial number of kids for `person1` using `print(f'Kids: {person1.num_kids}')`.5. Call the `inc_num_kids()` method on the `person1` instance to simulate the arrival of a new baby, which increments the number of kids.6. Print the updated number of kids for `person1` using `print(f'New baby, kids now: {person1.num_kids}')`.7. Execute the Python code to see the output, which displays the initial and updated number of kids for the person.1class PersonInfo: 2 def __init__(self): 3 self.num_kids = 0 4 5 def inc_num_kids(self): 6 self.num_kids += 1 7 8# Create an instance of PersonInfo 9person1 = PersonInfo() 10 11print(f'Kids: {person1.num_kids}') 12 13person1.inc_num_kids() 14 15print(f'New baby, kids now: {person1.num_kids}') 16Output :

Exercise 2: Create class Account with following instance variable and methods. Instance variables: id, name, balance Constructors: Account(String:id, String:name), Account(String:id, String:name, int: balance) Methods: getld(), getName(), getBalance(), credit(int: amount), debit(int: amount), TransferTo(Account:another, int:amount), toString() credit(int: amount):add amount to balance and return balance. debit(int: amount): if amount<=balance, subtract amount from balance else print amount exceeded and return balance.

The following is a Design Patterns: Singleton Pattern project with this UML class diagram. Please explain the UML class diagram as shown in image:
Java - Polymorphism Create a class named “Shape” that has the abstract methods getArea() and getPerimeter(). Create classes named “Rectangle”, “Square”, and “Circle”. Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. For rectangle, create attribute length and width. For square, side. For circle, radius. Inputs 1. Char input for Shape type (R/S/C) 2. Dimensions of specific type of Shape C 5 Sample Output Shape(R/S/C): R Length: 10 Width: 50 Area: 500.00 Perimeter: 120.00

Java Programing Design class CarInLine, with the following specifications: The class has two instance variables: arrivalTime and DepartureTime, stored as integers. Define a constructor that accepts an integer as an argument representing the arrival time, in which you set the departure time to zero, marking the beginning of a simulation. Create an appropriate set and get methods for the two instance variables. Implement a method totalTime() that returns an integer value representing the time spent in the queue, as the difference between the departure time and the arrival time. Define ten queues, simulating the functionality of the process, increasing the number of cashiers from one, and collecting the average waiting time for each scenario. Each simulation will work with the same number of cars, which is considered 100. The maximum number of cashiers/toll booths is 10. Create the queue with link-based implementation. Create each queue with the corresponding number of cashiers,…

Design a class named LinearEquation for a 2 × 2 system of linear equations: The class contains: ax + by = e cx + dy = f ■ Xx= ed - bf ad - bc y = af - ec ad – bc Private data fields a, b, c, d, e, and £. ▪ A constructor with the arguments for a, b, c, d, e, and f. ▪ Six getter methods for a, b, c, d, e, and f. ▪ A method named isSolvable () that returns true if ad – be is not 0. ▪ Methods getX() and getY() that return the solution for the equation. Draw the UML diagram for the class then implement the class. Write a test program that prompts the user to enter a, b, c, d, e, and f and displays the result. If ad - bc is 0, report that "The equation has no solution."
