DCIT 308 Individual Assignment

This is a Java console program that simulates request handling at a Ghana service centre. It uses a normal circular queue, a correction deque, an urgent priority queue, and an action stack.

Requirements

• Java JDK installed
• javac and java available in your terminal

Check your Java installation:

javac -version
java -version

How to Run

From the project root directory, compile all Java files:

javac src/*.java

On Windows PowerShell, this also works:

javac src\*.java

Run the simulator with the sample CSV file:

java -cp src GhanaServiceSimulator data/requests_sample.csv

On Windows PowerShell:

java -cp src GhanaServiceSimulator data\requests.csv

You can also run it from inside the src folder:

cd src
javac *.java
java GhanaServiceSimulator ../data/requests_sample.csv

Input Data

The simulator expects a CSV file with this header:

requestId,arrivalOrder,location,serviceType,urgencyLevel,estimatedMinutes,needsCorrection,notes

Available example files are in the data folder:

• data/requests_sample.csv
• data/requests_template.csv
• data/requests.csv

To use your own dataset, replace the path in the run command:

java -cp src GhanaServiceSimulator data.csv

Expected Output

The program prints each served request, then a final report showing total served requests, urgent/correction/normal counts, overflow count, remaining queue sizes, and average estimated minutes served.
