Thanks for contributing new Java and Node.js projects to the dataset — expanding language diversity is valuable for DevPath and the overall project structure is reasonably well organized.

However, there is one important blocking issue before this can be merged:

The dataset entries reference starter code files:

• starter_code/library_management.java
• starter_code/realtime_chat_app.js

but those files are not included in the PR. This creates broken references inside the application and compromises dataset integrity.

Please add the missing starter code files and verify:

• the JSON remains valid
• the projects render correctly in the UI
• recommendations still work as expected

Additional improvement suggestions:

• make roadmap steps more specific/educational
• consider using structured resource objects instead of plain strings for URLs in future dataset entries

Once the missing starter files are added and verified, this PR will be much closer to merge-ready.

Thanks for reviewing the PR and pointing this out.

I’ve now added the missing starter code files:

• starter_code/library_management.java
• starter_code/realtime_chat_app.js

I also verified:

• JSON validity
• project rendering in the UI
• recommendation flow behavior

I appreciate the additional suggestions regarding roadmap specificity and structured resource objects — I’ll keep those improvements in mind for future contributions.
