The main difference between a Junior Java Developer Intern and a Junior Java Developer lies in experience and responsibilities. Interns are typically students or recent graduates gaining practical experience, while Junior Developers are full-time employees with more responsibilities and ongoing projects. Internships serve as a stepping stone toward a full developer role, which requires more skills and commitment.
