anushasarees

The document contains Java code that defines two classes: 'team' and 'game', with attributes and methods for managing team and game data. It includes constructors, getters, validation methods for email and game date, and testing functionality to ensure equality and validity. Additionally, it reads input from a file to create team and game objects and validate their attributes.
