Java: The Primary Language for Minecraft Modding

Java is the main programming language used for creating Minecraft mods. Since Minecraft itself is built in Java, modding frameworks like Forge and Fabric use Java to hook into the game’s existing code structure. This makes Java the most natural choice for mod development.

Most Minecraft modders work with established frameworks rather than coding from scratch:

  • Minecraft Forge – The most popular and mature modding platform, offering extensive APIs and tools
  • Fabric – A lighter, more modern alternative that updates quickly with new Minecraft versions
  • Quilt – A newer fork of Fabric with additional features and community focus

Alternative Languages and Tools

While Java dominates, other options exist for specific use cases:

  • Kotlin – Fully compatible with Java frameworks and increasingly popular among developers
  • Scala – Less common but supported by some modding platforms
  • MCreator – A visual tool that generates Java code, perfect for beginners without programming experience
  • Bedrock Edition – Uses C++ and supports add-ons through JavaScript/TypeScript

Getting Started with Java Modding

New modders typically need to learn Java fundamentals first, then familiarize themselves with their chosen framework’s documentation and APIs. The modding community provides extensive tutorials and examples to help beginners understand concepts like block registration, item creation, and world generation. If you’re looking to dive into the world of Minecraft after learning about modding, there are plenty of ways to experience the game online.

TL;DR

Java is the primary language for Minecraft mods, used with frameworks like Forge and Fabric. Alternatives include Kotlin, visual tools like MCreator, and C++ for Bedrock Edition.
