The document provides Java code for creating a simple Snake game with two classes: 'board' and 'snake'. The 'board' class handles the game's graphics, apple generation, and snake movement, while the 'snake' class creates the game window and initializes the board. Users must create a folder containing necessary image assets before running the game code.
