  • What can I do with Java 1.4?
    3 projects | /r/java | 11 Feb 2022
    I made one (Before realizing it'd already been done) to backport newer language features to Java 8 and it was pretty easy to bundle it up as a maven plugin. But going back all the way to 4 will be a notable increase in difficulty. Retrolambda goes to 1.5 but not all the way to 4. You could hypothetically add a layer on top of it to support 1.5 -> 1.4. That or roll a fork of it.

What are some alternatives?

When comparing λ and Functional Java you can also consider the following projects:

Javaslang - vʌvr (formerly called Javaslang) is a non-commercial, non-profit object-functional library that runs with Java 8+. It aims to reduce the lines of code and increase code quality.

jOOλ - jOOλ - The Missing Parts in Java 8 jOOλ improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.

Fugue

StreamEx - Enhancing Java Stream API

derive4j - Java 8 annotation processor and framework for deriving algebraic data types constructors, pattern-matching, folds, optics and typeclasses.

cyclops-react - An advanced, but easy to use, platform for writing functional applications in Java 8.

underscore-java - java port of Underscore.js

protonpack - Stream utilities for Java 8
