A Java-based interpreter for a custom-designed concurrent toy programming language, built using advanced programming concepts and architectural patterns.
This interpreter was developed incrementally as part of university coursework 🎓.
It supports execution of programs written in a custom-defined language, demonstrating key programming principles and complex features 💡.
- 🧱 Model-View-Controller (MVC) architecture
- 👨💻 Object-Oriented Programming (OOP): interfaces, inheritance, polymorphism
- 🧵 Concurrency: Multi-threaded execution with
forkstatements and Java'sExecutorService - 🗃️ Heap Management: Dynamic memory allocation with garbage collection
- 📂 File Operations: Open, read, write, and close files using Java I/O streams
- 🧬 Functional Programming: Recent labs applied high-order functions for modular, side-effect-free code
- 🧪 Type Checking: Static type checking before program execution
- 🖼️ Graphical User Interface (GUI): Interactive GUI built with JavaFX
This project demonstrates advanced technical skills through:
- 🧰 Implementation of custom data structures (Stack, Dictionary, List) using Java generics
- 🔍 Simulation of complex language features (expression evaluation, conditional logic)
- 🤝 Management of concurrent program states with shared resources (Heap, FileTable)
- ✅ Integration of static type checking to ensure program correctness
- 📝 Comprehensive logging for debugging and program state visualization

- 🧾 Execution Stack – statement execution order
- 🧮 Symbol Table – variable-value bindings
- 🧠 Heap Table – dynamic memory (referenced data)
- 📤 Output List – printed outputs during execution
- 📁 File Table – open files and I/O stream data
The JavaFX interface allows users to:
- 📝 Select predefined example programs
- 🔄 Visualize execution steps interactively
- 👀 Inspect heap memory, symbol tables, execution stacks, file tables, and outputs in real-time
