How It All Started

“What is Minecraft Java?” You probably hear that tons of times in your daily life.

Minecraft began as a passion project by Swedish programmer Markus “Notch” Persson in 2009. The very first version, later referred to as “Java Edition Pre-Classic,” was created in just six days. On May 17, 2009, Notch shared this early build on the TIGSource forums, where it quickly captured the imagination of early players.

The game wasn’t even called “Minecraft” at first – Notch originally named it “Cave Game.” The earliest public version featured just a handful of blocks (primarily grass, cobblestone, and dirt) with no inventory system or gameplay objectives. Despite these limitations, players were immediately drawn to its open-ended creativity.

What made the early Minecraft so revolutionary was its procedural world generation and the freedom it gave players. As user “Whisski” famously commented on the TIGSource forums: “This is awesome. I can see myself spending hours just building stuff in this.”

The game evolved rapidly through development stages:

• Pre-Classic (May 2009)
• Classic (May-November 2009)
• Indev (December 2009-February 2010)
• Infdev (February-June 2010)
• Alpha (June-December 2010)
• Beta (December 2010-November 2011)

By the time the full release of Minecraft 1.0 launched on November 18, 2011, at the first MineCon event in Las Vegas, the game had already sold over 4 million copies while still in beta. Notch’s company Mojang was eventually acquired by Microsoft in 2014 for $2.5 billion – an incredible journey for a game that started as a simple Java project.

Differences from Bedrock Edition

When Microsoft acquired Mojang, they eventually created Bedrock Edition – a cross-platform version of Minecraft written in C++ to run on consoles, mobile devices, and Windows 10/11. This has led to two main versions of Minecraft existing simultaneously, with some key differences between them:

Game Mechanics

• Redstone behavior differs between versions, with Java Edition having more consistent and sometimes exploitable redstone mechanics that technical players prefer
• Combat timing varies slightly, with Java Edition featuring the original attack cooldown system
• Mob spawning rules and despawning distances have subtle variations
• Hardcore mode is exclusive to Java Edition
• World generation can differ slightly between versions

Technical Aspects

• Java Edition supports free, community-created mods and texture packs without restrictions
• Java Edition servers offer more customization options and plugin support
• Java Edition receives experimental features first through “snapshots”
• Bedrock Edition generally performs better on lower-end hardware
• Java Edition only runs on Windows, macOS, and Linux

Multiplayer

• Java Edition uses the traditional server-client model for multiplayer
• Bedrock Edition uses a friend-based system with “Realms”
• Cross-play exists within each ecosystem but not between Java and Bedrock (with limited exceptions)

Monetization

• Java Edition has a one-time purchase cost with all content included
• Bedrock Edition features the Minecraft Marketplace where players can purchase skins, worlds, and texture packs

One of the biggest advantages of Java Edition is the thriving modding community. Mods like OptiFine for performance improvements, Forge as a modding framework, and complete overhauls like RLCraft have given the game incredible longevity and depth that wouldn’t have been possible in the more controlled Bedrock ecosystem.

How It Was Made: The Technical Foundation

Minecraft Java Edition was built using, as the name suggests, the Java programming language. This choice had profound implications for how the game was developed and how it runs.

The game was created using several key technologies:

LWJGL (Lightweight Java Game Library)

LWJGL serves as the foundational framework that allows Minecraft to interface with OpenGL, OpenAL (for sound), and input devices. It essentially provides Java applications with access to high-performance cross-platform libraries that are commonly used for game development.

OpenGL

For graphics rendering, Minecraft uses OpenGL (Open Graphics Library), a cross-platform API for rendering 2D and 3D graphics. Early versions of Minecraft used OpenGL 1.1, though it has been updated over the years. The game uses relatively simple rendering techniques, which contributes to its distinctive blocky aesthetic.

Java Libraries

Minecraft relies on several Java libraries, including:

• LWJGL (as mentioned above)
• Paulscode Sound System for audio management
• Guava from Google for additional data structures and utilities
• Standard Java libraries for networking, file handling, and more

In the game’s architecture the world is divided into chunks (16×16×256 blocks), which are generated procedurally using noise functions like Perlin noise. This approach allows for virtually infinite worlds while keeping memory usage manageable.

Minecraft’s code architecture has evolved over time, especially as the game transitioned from Notch’s initial implementation to a team-developed project. The rendering system uses what’s known as a “chunk-based renderer,” where only the visible parts of the world are processed and sent to the GPU.

Why Minecraft Java Performance is Inferior to Bedrock

Java Edition has earned a reputation for being less performant than Bedrock Edition, and there are several technical reasons for this:

Java Virtual Machine Overhead

Minecraft Java runs on the Java Virtual Machine (JVM), which adds a layer of abstraction between the game code and the hardware. While the JVM provides cross-platform compatibility and memory management, it introduces overhead that can impact performance, particularly with memory usage and garbage collection.

Rendering Technology Differences

• Java Edition uses OpenGL with a more traditional rendering approach
• Bedrock Edition uses RenderDragon, a custom rendering engine optimized for performance across multiple platforms

RenderDragon (Bedrock’s engine) was built specifically for cross-platform optimization and takes better advantage of modern GPU features. It employs more efficient memory management and rendering techniques, resulting in better frame rates, especially on lower-end devices.

Multi-threading Limitations

The original Minecraft Java code wasn’t designed with extensive multi-threading in mind. While improvements have been made over the years, Bedrock Edition was built from the ground up to better utilize multiple CPU cores for things like chunk loading and rendering.

C++ vs. Java

Bedrock Edition is written in C++, which generally allows for more direct hardware access and optimization compared to Java. C++ doesn’t require a virtual machine intermediary, which can reduce overhead in memory-intensive applications like Minecraft.

Despite these performance disadvantages, many players still prefer Java Edition for its modding capabilities, consistent redstone mechanics, and the fact that it receives experimental features first through snapshot releases.

What is Java?

Since Minecraft Java Edition is built on the Java programming language, it’s worth understanding what Java actually is and why it was chosen for Minecraft’s development.

Java is a high-level, class-based, object-oriented programming language designed to have as few implementation dependencies as possible. James Gosling (not related with Ryan Gosling) created it while at Sun Microsystems (now owned by Oracle) and released in 1995.

The key principle behind Java is “write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without recompilation. The Java Virtual Machine (JVM) interprets something known as compiled Java bytecode.

Key Features of Java:

• Platform Independence: Java programs run on the JVM, not directly on the hardware
• Object-Oriented: Everything in Java is an object, making code organization more intuitive
• Automatic Memory Management: Includes garbage collection to handle memory allocation
• Strong Type System: The programmer declares variables before using with specific data types
• Rich Standard Library: Comes with extensive built-in functionality
• Security Features: Built with network computing in mind

How Minecraft Java Got Many People Into Programming

One of the most remarkable aspects of Minecraft Java has been its role as a gateway into programming for countless young people. I count myself among them – Minecraft was what first sparked my interest in coding.

The modifiable nature of Java Edition created a perfect entry point for aspiring programmers. Here’s how:

Mod Development

Creating mods for Minecraft became many players’ first programming experience. Systems like Forge and Fabric provided frameworks that allowed even beginners to add new items, blocks, or mechanics to the game. The immediate visual feedback of seeing your code manifest as something tangible in a familiar game world proved incredibly motivating.

Server Plugins

Running Minecraft servers required learning about Java, networking, and server administration. Many young server owners started by making simple plugins with Bukkit or Spigot and gradually developed more advanced programming skills.

Redstone Computing

Even without writing code, Minecraft’s redstone system introduced players to computational thinking. Building logic gates, memory cells, and even functioning computers within Minecraft taught fundamental programming concepts like boolean logic, variables, and control flow.

Community Learning Resources

The Minecraft community created extensive tutorials, forums, and YouTube channels dedicated to teaching Java programming through Minecraft modding. Resources like “Learn to Program with Minecraft” by Craig Richardson became popular entry points for young programmers.

Success Stories

Many professional developers today cite Minecraft as their introduction to programming. For example, the creator of the popular mod “ComputerCraft,” Dan200, went on to work professionally in game development. Similarly, many prominent Minecraft mod developers have transitioned to careers in software engineering.

My own journey followed this path – starting with simple mods that added new ores to the game, then moving to more complex server plugins, and eventually pursuing computer science more formally. The satisfaction of creating something in Minecraft that I could share with friends provided motivation that traditional programming exercises never could.

Minecraft Java Edition’s accessibility, creativity, and strong community support created the perfect environment for budding programmers to flourish. The game’s legacy extends far beyond entertainment – it has shaped a generation of developers who first discovered the joy of coding through placing blocks in a virtual world.
