You want to create a class Rectangle that stores width and height and calculates area. Which is the best way to do this?
ACreate two separate variables width and height outside any class
BCreate a class with width and height fields and a method that returns width * height
CUse only static methods without fields
DCreate a class with only a method that prints area without storing width and height
Step-by-Step Solution
Solution:
Step 1: Understand class purpose
Class should store data (width, height) and provide behavior (calculate area).
Step 2: Evaluate options
Only Create a class with width and height fields and a method that returns width * height stores data and calculates area properly; others miss data or proper design.
Final Answer:
Create a class with width and height fields and a method that returns width * height -> Option B
Quick Check:
Class design = Store data + behavior [OK]
Quick Trick:Classes hold data and methods for related tasks [OK]
Common Mistakes:
MISTAKES
Using variables outside classes
Ignoring data storage
Using only static methods
