[1008] UML대로 구현하기

 

객체지향설계 시간에 UML을 배우고 나서 draw.io 프로그램을 이용해서 직접 관계를 따져 그려보고 이것을 참고해서 아래와 같은 python 코드로 구현하였다. 위의 UML을 그릴 때 표현된 선은 아래와 같은 클래스들의 관계에 따라 선의 종류를 바꿔서 표현하였다.

위의 UML대로 구현한 Python 코드는 아래와 같다.

class Customer:
    def __init__(self, name, address):
        self.name = name
        self.address = address
        print("Your Name : ",self.name)
        print("Your address : ",self.address)
 
    print ("new Customer's Order")
   
class OrderDetail:
    def __init__(self, quantity, taxStatus):
        self.quantity = quantity
        self.taxStatus = taxStatus
 
    def calcSubTotal(self):
        total = self.quantity * 1000
        print("")
        print("SubTotal Prize is ...", total, 'won')
    
    def calcWeight(self):
        total = self.quantity * 500
        print("Weight is...", total, 'g')
 
    def clacTax(self):
        total = self.quantity * self.taxStatus
        print("Total taxStatus is...", total, 'won')
 
 
class Order:
     def __init__(self, date, status):
         self.date = date
         self.status = status
 
         print(self.date, " / " ,self.status)
         check = input("show Order Detail?(Y/N) : ")

원래는 추상적인 클래스들의 정보만 제공이 되고 구체적인 동작은 제시해주지 않았기 때문에 UML을 구현한대로 내가 만들고 싶은 동작대로 구현을 해 보았다. Python에 조금이나마 익숙해진 것 같아 좋은 경험이 되었다.

 

아래에 첨부된 사진은 위의 코드를 동작시켰을 때 UML대로 관계를 가지고 순차적으로 실행되는 것을 볼 수 있다.
