J2ME
A Java mobile platform specification introduced by Sun Microsystems in 1999, designed for feature phones with strictly limited memory and computing resources. It enables Java applications and games to run on devices with minimal hardware configurations.

A Reddit user used a single-sentence prompt to have Claude Opus 5.5 produce a playable pseudo-3D shooter game for an old-school J2ME feature phone.
J2ME (Java 2 Micro Edition) is a Java mobile platform specification introduced by Sun Microsystems in 1999, designed specifically for feature phones with strictly limited memory and computing power.
Typical J2ME devices had less than 1MB of heap memory, CPU clock speeds below 100MHz, and generally lacked a floating-point unit (FPU).
Due to the lack of an FPU, J2ME game developers at the time commonly used fixed-point or pure integer mathematics to implement geometric operations, typically scaling values up by 1024 or 4096 times and storing them as integers.
A JAR (Java ARchive) is essentially a ZIP compressed package containing compiled bytecode, resource files, and a manifest descriptor; J2ME also requires an accompanying .jad descriptor file.
Many early J2ME devices had a hard size limit on individual application packages, often no more than 64KB or 128KB.
