Question

Enlistee and Private Classes

Write an Enlistee class that keeps data attributes for the following pieces of information:

• Enlistee name

• Enlistee number

Next, write a class named Private that is a subclass of the Enlistee class. The Private class should keep data attributes for the following information:

• Platoon number (an integer, such as 1, 2, or 3)

• Years of service (also an integer)

Write the appropriate accessor and mutator methods for each class.

Once you have written the classes, write a program that creates an object of the Private class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object and then use the object’s accessor methods to retrieve it and display it on the screen.

Using python please.

Solution: I have written comments for each line for better understanding.

# class Enlistee
class Enlistee:
    # init method or constructor   
    def __init__(self, name,number):
        self.name = name
        self.number = number
    
    # Retrieves instance variable      
    def getName(self):      
        return self.name
    
    # Retrieves instance variable    
    def getNumber(self):
        return self.number
    
    # Mutator method
    def setName(self,name):
        self.name = name
    
    # Mutator method    
    def setNumber(self,number):
        self.number = number
        
# Private class inherits Enlistee
class Private(Enlistee):
    # init method or constructor 
    def __init__(self, name, number,platoon_number,service_year):
        self.platoon_number = platoon_number 
        self.service_year = service_year 
  
        # invoking the __init__ of the parent class  
        Enlistee.__init__(self, name, number)
        
    # Retrieves instance variable
    def getPlatoon_number(self):
        return self.platoon_number
    
    # Retrieves instance variable    
    def getService_year(self):
        return self.service_year
    
    # Mutator method     
    def setPlatoon_number(self,platoon_number):
        self.platoon_number = platoon_number
    
    # Mutator method     
    def setService_year(self,service_year):
        self.service_year = service_year
        

# Taking iinput from user
name = input("Enter name of Enlistee: ")
number = int(input("Enter number of Enlistee: "))
platoon_number = int(input("Enter platoon number of Enlistee: "))
service_year = int(input("Enter service year of Enlistee: "))

# Creating object with the help of given values
obj = Private(name,number,platoon_number,service_year)

# Printing value using accessor methods
print("\n\nName of Enlistee: "+obj.getName())
print("Number of Enlistee: "+str(obj.getNumber()))
print("Platoon Number of Enlistee: "+str(obj.getPlatoon_number()))
print("Service Year of Enlistee: "+str(obj.getService_year()))
