Step-by-Step Solution
Solution:
Step 1: Identify nested if-else problem
Using many if-else instead of polymorphism is called Switch Statements Anti-pattern.Step 2: Understand why problematic
This reduces extensibility and makes code complex to maintain, matching Switch Statements Anti-pattern; it reduces extensibility and increases complexity.Final Answer:
Switch Statements Anti-pattern; it reduces extensibility and increases complexity -> Option DQuick Check:
Nested if-else vs polymorphism = Switch Statements Anti-pattern [OK]
Quick Trick: Replace nested if-else with polymorphism [OK]
Common Mistakes:
MISTAKES- Confusing with God Object
- Thinking magic numbers relate here
- Mixing with shotgun surgery
