Below is the source code for ExampleGame. For simplicity, ExampleGame does not actually contain code to play a game. It simply retrieves or updates a user's high score.
To see what the user's current high score value is, you could run:
java ExampleGame get
To set a new high score value for the user, you could run:
java ExampleGame set score
To retrieve the user's current high score, ExampleGame simply instantiates a HighScore object and makes a call to its getHighScore method. To set a new high score for the user, ExampleGame instantiates a HighScore object and calls setHighScore, passing it the user's new high score.
