Pattern-matching across different languages

Tue, 05 Aug 2025 07:40:40 +0000

Pattern matching is a major feature in software development. While pattern matching applies in several locations, its current usage is limited to switch case blocks. I want to compare the power of pattern matching across a couple of programming languages I’m familiar with in this post.

I assume that every reader is familiar with the switch case syntax inherited from C. In short:

The switch clause references a value-returning statement
Each case clause sets another statement; if the value matches the statement, it executes the related block
case clauses are evaluated in order. The first clause that matches gets its block executed
In C, case clauses are fall-through; you need to explicitly break to escape the switch, otherwise, the next case is evaluated

Java’s pattern matching

I’ll start with Java, as it was the first programming language I used in a professional context.

Why Scala?

At Quantexa , we love Scala. This may be the first dedicated article on Foojay.io about Scala. I hope my colleagues and I can add more in due course.

Scala is built on the Java Virtual Machine (JVM). For foojay.io readers, this is “stating the bleeding obvious,” but it means it compiles to Java bytecode and runs on the same runtime environment as Java. This brings significant enterprise scalability, resilience and big data ecosystem benefits.
