sJava implements static s expressions for Java and compiles them away so runtime code is normal Java; a hello world example runs and prints hello world. It provides hygienic macros that run at compile time, take and return token trees, and use type-aware macro expansion so macros can inspect method and class context. Built macros include println, a for‑each that chooses index vs iterator, a with helper, and a macro that generates double dispatch. It uses NewBytecode to emit correct JVM instructions and it works end to end.
