Is your feature request related to a problem? Please describe.
Currently, Javastic lacks a live coding experience. Learners must switch between the website and local IDEs or third-party playgrounds to try out Java code, which breaks focus and adds friction in the learning process.

Describe the solution you'd like
Add an integrated code editor within the website where users can:

• Write and test Java code snippets
• See instant output
• Run common templates (e.g., Hello World, loops, OOP)
• Possibly get syntax suggestions or error highlights (basic)

Describe alternatives you've considered

• Linking to external platforms like Replit or JDoodle (but embedding it inside would be more seamless)
• Asking users to install a local IDE (not beginner-friendly)

Additional context
Adding a code editor will make the platform more interactive and effective for learning. It aligns with modern edtech standards and improves retention through practice-based learning.

Some potential open-source editors you could explore:

• Monaco Editor – used in VS Code
• Ace Editor
• CodeMirror
