Refactoring Java Spring Boot Code: Eliminating If-Else Statements for Cleaner, Extensible Logic
5 min readJun 17, 2024
When working with Java Spring Boot applications, one common issue developers face is the overuse of if-else statements. While if-else logic is often the simplest way to implement conditional behavior, it can lead to code that is difficult to read, maintain, and extend. This article will explore various strategies to refactor if-else statements, leading to cleaner and more extensible code.
Why Avoid If-Else Statements?
1. Readability:
- If-else chains can be difficult to follow, especially when they grow in size.
- Nested if-else statements further complicate understanding.
2. Maintainability:
- Changes in logic often require modifying multiple conditions scattered throughout the code.
- The likelihood of introducing bugs increases with each new condition.
3. Extensibility:
- Adding new conditions means adding more if-else statements, which can become cumbersome.
- If-else logic is not easily adaptable to changing requirements.
