🚫 Stop Writing Repetitive Conditions: Try Pattern Matching Instead (Java 21+)
4 min readApr 12, 2025
In traditional Java, it’s common to see repetitive instanceof checks and type casts scattered throughout conditional logic. While this might work, it leads to verbose code, fragile logic, and poor readability.
With Java 21, pattern matching has become a first-class feature — allowing you to cleanly match object types, extract values, and make decisions without repetition.
In this article, we’ll show how to refactor repetitive conditional logic using Java 21’s pattern matching for instanceof and switch — with practical examples to help you write cleaner, more expressive code.
Let’s get started!
