Question

Create a Class Diagram for a Rectangle class that has one constructor with two int parameters length, width, a public int value return function get_area, one private void function calculate_area, and three private int variables length, height, and area. Use + to denote public and - to denote private.

Answer 1

A class diagram for the Rectangle class that includes attributes, constructor, and methods.

Step-by-step explanation:

Class Diagram for Rectangle Class

• 
  
• +length: int
• 
  
• +width: int
• 
  
• -length: int
• 
  
• -width: int
• 
  
• -area: int
• 
  
• 
  
• 
  
• +Rectangle(length: int, width: int)
• 
  
• +get_area(): int
• 
  
• -calculate_area(): void

The class diagram for the Rectangle class is displayed above. It includes the public attributes length and width, as well as the private attributes length, width, and area. The class also has a constructor that takes two int parameters, a get_area() method that returns the area of the rectangle, and a calculate_area() method that is used internally to calculate the area.
