Urgent Java Project Repair

I'm urgently looking for an experienced java developer to rectify compilation and runtime errors plaguing my current project. To be successful, your application should include:

- A detailed project proposal on how you plan to tackle and overcome these issues.

Despite not using any particular Java libraries or tools, familiarity with a broad range of such will be an advantage. This project awaits a diligent problem-solver ready to breathe life back into it.

I have attached all possible files and images needed to view the task at hand.
