JavaVirtualMachine

Java compiler/interpreter project built with Java and JavaCC.

Overview

JavaVirtualMachine is an academic project focused on compiler and interpreter design.
It includes parsing, syntax analysis, type checking, interpretation, and execution logic for a custom Java-like language.

The project demonstrates key concepts of language processing and software construction, including lexical analysis, parsing, semantic checks, and runtime execution.

Features

• Lexical and syntax analysis
• JavaCC-based parser
• Type checking
• Interpretation and execution logic
• Compiler/interpreter project structure
• Java-based implementation

Tech Stack
