## Overview

This is a console-based sports tournament manager. The user registers teams, adds players and coaches, views tournament details, enters match scores, and views results and the points table. Main.java coordinates this workflow; Tournament and Team hold in-memory state, while Match applies scoring rules. The excerpts show no persistent storage. Coach details are created and displayed, but no association with a team or tournament is visible in the sampled source.
