The Time Table Generator project in Java is a desktop or web-based application designed to automatically create organized and conflict-free schedules for classes, teachers, and classrooms in an educational institution. Instead of manually preparing a schedule, which is time-consuming and prone to conflicts, this project allows administrators to automate the process using predefined rules and constraints.

Objective

To develop a system that automatically generates a class timetable based on input data such as subjects, teachers, time slots, and classrooms, while handling constraints like teacher availability and avoiding overlaps.

Key Features

Input Module: Allows admin to enter details such as:

List of classes and sections

Subjects offered for each class

Teachers assigned to each subject

Available classrooms and time slots

Number of periods per day and days per week

Constraint Handling:

Ensures no teacher is double-booked in different classes at the same time

Prevents multiple classes from using the same room at the same time

Ensures classes have no duplicate subjects in the same day or period

Scheduling Algorithm:

Uses logic and basic algorithms (e.g., greedy, backtracking) to place subjects in available slots

Considers teacher availability, class subject requirements, and period limits

Output Generation:

Displays the generated timetable in a readable format (for each class or teacher)

Optionally exports timetable as PDF or Excel for printing and sharing

User Roles:

Admin: Manages inputs and generates timetable

Teacher: Views individual schedules

Student: Views class timetable

Technologies Used

Java: Core language for implementing logic

Java Swing or JavaFX: For building the graphical user interface

JDBC with MySQL or SQLite: For storing input data and generated timetables

Collections (ArrayList, HashMap): For managing data like subject-teacher mappings

Example Workflow

Admin adds subjects and assigns them to classes and teachers.

System checks teacher availability and classroom occupancy.

Timetable is generated, ensuring each class gets all its subjects scheduled without clashes.

Timetables are made available for download or displayed on the interface.

Possible Enhancements

Integration with online school portals

Dynamic timetable updates for substitutions

Notification system for timetable changes

Web or mobile version for better accessibility

Conclusion

The Time Table Generator in Java is a useful tool for educational institutions. It reduces the manual effort involved in timetable creation and ensures efficient, error-free scheduling. It also introduces concepts like constraint handling, scheduling logic, and data management in Java, making it a great learning project for students and developers.
