The Hospital Management System is a Java-based GUI application that enables efficient management of hospital operations. It offers a user-friendly interface for doctors and patients to access and manage crucial information. Doctors can view patient lists, appointments, medical histories, and test reports. Patients can access their medical history, test reports, and appointments. This project simplifies hospital administration, enhances communication, and improves overall efficiency..
