Classes, Interfaces and Enumerations

1. The Match class represents a cricket match, with properties such as ID, title, venue, start time, teams, status, and scorecard.
2. The Team class represents a cricket team, with properties like ID, name, and a list of players.
3. The Player class represents a cricket player, with properties such as ID, name, and role.
4. The Scorecard class represents the scorecard of a match, containing team scores and a list of innings.
5. The Innings class represents an innings in a match, with properties like ID, batting team, bowling team, and a list of overs.
6. The Over class represents an over in an innings, containing a list of balls.
7. The Ball class represents a ball bowled in an over, with properties such as ball number, bowler, batsman, and result.
8. The MatchStatus enum represents the different statuses of a match, such as scheduled, in progress, completed, or abandoned.
9. The MatchService class manages the matches in the system, providing methods to add, retrieve, and update match information. It follows the Singleton pattern to ensure a single instance of the service.
10. The ScorecardService class manages the scorecards of matches, allowing the creation, retrieval, and update of scorecards and their associated data, such as innings and scores. It also follows the Singleton pattern.
11. The CricinfoSystem class serves as the main entry point of the system, integrating the match and scorecard services and providing high-level methods for interacting with the system.
