online course registration in java
introduction
The Online Course Registration System allows students to enroll in courses using a Java application with GUI support.
It includes features such as user login, course catalog display, registration form validation, and schedule conflict detection. Admins can manage course offerings, assign instructors, and view student registrations.
This system automates the tedious manual course selection process used in colleges and universities. It provides a structured interface for managing academic schedules, course capacities, and student preferences, making it an ideal academic project to understand real-time scheduling and data management.
