## What is Jedona?

Write Java code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets!

Java is a general-purpose programming language that is class-based and object-oriented. It is intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.

Features:
- Compile and run your program
- View program output or detailed error 
- Custom keyboard for easy input of frequently used characters
- Optimized for connecting with external physical/bluetooth keyboard
- Advanced source code editor with syntax highlighting, bracket completion and line numbers
- Import files from your personal iCloud Drive account and export files that you create.

Limitations:
- Internet connection is required for compilation
- Maximum program running time is 20s
- One file can be run at a time
- Some file system, network and graphics functions may be limited
- This is a batch compiler; interactive programs are not supported. For example, if your program provides an input prompt, enter the input in the Input tab prior to compilation.

- Compile and run Java programs
- View program output and errors
- Custom keyboard for special characters

*2025-05-23, version 3.3.2*
