Class DatabaseConnection

java.lang.Object

simu.dao.DatabaseConnection

public final class DatabaseConnection
extends Object

Loads connection settings from src/main/resources/db.properties and provides JDBC Connections on demand. Lightweight by design — no pooling. Each get() opens a fresh connection. For an academic simulator this is more than enough; the application only persists once per run, at the end. If the properties file is missing or the database is unreachable, get() throws a SQLException so callers can decide whether to surface or swallow the error (we swallow it in the Controller so a DB outage does not crash the simulation).
