Cyclops is a functional programming library for Java 8+ providing advanced purely functional data structures, monads, monad transformers, and reactive streams integration. It offers an easy-to-use API for functional and asynchronous application development on the JVM.
Use cases
- write functional code in Java
- use monads like Option, Either, and Try in Java
- work with immutable persistent collections
- process streams reactively and asynchronously
- avoid nulls and exceptions with functional error handling
- lazy evaluation with Eval
- structural pattern matching in Java
When to choose
- you want functional programming abstractions on the JVM
- you need type-safe alternatives to Optional and exceptions
- you want reactive streams with functional data structures
When to avoid
- you are on a modern Java codebase already using standard streams and records
- you prefer lightweight single-purpose libraries
- you need a library under very active development
