Wordle

This is a Java implementation of the popular game Wordle. The game features a 5x6 grid where players attempt to guess a 5-letter word within six attempts.

Core Concepts

1. File I/O: Used to save and load game states, as well as read a CSV file containing a list of 5-letter words. The FileUtil class handles the creation and reading of game state files, while WordleReader reads the word list.
2. Collections: Utilized in implementing the undo functionality. A history list stores the grid states after each guess, enabling users to undo their last guess.
3. 2D Array: The main game grid is a 2D array of WordleCharAndColor objects, which store the character and color data for each cell.
4. JUnit Testable Component: The game includes a suite of 11 test cases that test the main functionalities of the Wordle class, as well as the encapsulation of the 2D array and history grid.

Implementation Overview

• Wordle.java: Contains the main game logic, managing game state variables and implementing game functions such as reset and undo.
• RunWordle.java: Sets up the user interface, creating the game frame and buttons, and setting up their action listeners.
• WordleCharAndColor.java: A helper class used to create the main game grid, storing the character and color data for each cell.
• WordleReader.java: Implements File I/O to read in the CSV file containing the word list.
• GameBoard.java: Connects the front-end and back-end, reflecting user inputs in the game state and updating the user interface to match.
• GameState.java: Stores the current game state, including the Wordle object and various game variables, for saving and loading.
• FileUtil.java: Implements File I/O to save and load game states.

Design Evaluation

This implementation features a strong separation of functionality, with different classes handling different aspects of the game. Private state is well-encapsulated, with instance variables generally being private and accessed through getter methods. Future refactoring may focus on making the paintComponent method more concise.

Playing the Game

To play the game, run the RunWordle.java file. This will open a new window with the game grid and control buttons. Enter your guesses using the keyboard and see how quickly you can guess the word!
