Welcome to my implementation of the classic game of Bull & Cows, written in Java and using JOptionPane for popups. This program allows the user to play the game by guessing a randomly generated secret number. The game includes an abstract class named Expression which provides the basic functionality of the game.
The program can be run by executing the `Game.java` file. You will need to have the latest version of Java installed on your system.
- The objective of the game is to guess a four-digit secret number that has been randomly generated by the program.
- The player will be prompted to enter a four-digit guess, and will be given feedback on the number of bulls (correct digits in the correct position) and cows (correct digits in the wrong position) in their guess.
- The player will keep guessing untill he gets the full number.
- To start the game.
- To make a guess, enter a four-digit number in the text field and press the guess button.
- The program will show you the number of bulls and cows in your guess.
- If you guess the secret number correctly, you win the game!
I hope you enjoy playing this game! Bull & Cows is a classic game that requires logical thinking and deduction skills. Let me know if you have any issues or suggestions for improvements!
