Purpose and Entry Points

This is a console-based Java railway reservation simulator. It models booking, cancellation, RAC, and waiting-list behavior rather than a web or service application. Likely execution begins in Ticket_Booking.java, with Ticket_System.java coordinating reservation operations.

Console Application Boundary

The system runs as a local Java process and interacts through standard input/output. There are no indicated HTTP endpoints, databases, cloud services, or external infrastructure. Application state is likely held in memory for the process lifetime.

Passenger Domain Model

Passenger.java represents the core booking subject: a traveler and associated reservation details such as identity, berth preference, ticket status, or allocated seat. This object is passed between booking and system-management logic.

Reservation Orchestration

Ticket_System.java is the likely central domain/controller component. It owns available confirmed berths, RAC capacity, waiting-list capacity, and passenger collections/queues. It applies the business rules that decide whether a passenger receives a confirmed ticket, RAC placement, or waiting-list placement.

Booking Flow

Ticket_Booking.java likely collects user choices from the console and invokes booking behavior in Ticket_System.java. The primary flow is:

1. Read passenger/request data.

2. Create a Passenger.java instance.

3. Attempt confirmed berth allocation.

4. Fall back to RAC, then waiting list when capacity is exhausted.

5. Print resulting ticket or queue status.

Cancellation and Queue Promotion

Cancellation is a critical control-flow stage managed by Ticket_System.java. Releasing a confirmed berth should permit RAC passengers to move into confirmed status; RAC availability can then allow waiting-list passengers to advance. Queue ordering is architecturally important to preserve reservation fairness.

Runtime and State Constraints

The material runtime is the Java console/JVM. The repository contains no persistence layer, so reservation records, berth inventory, RAC entries, and waiting-list queues are expected to be transient in-memory state within Ticket_System.java and related domain objects.
