Implement a Connect 4 game with two players and game logic

The assignment requires developing a Java program that allows two players to play Connect 4. The program should utilize a 2D array to represent the game board, which consists of six rows and seven columns. Users will input the column number where they want to drop their piece, and the program must validate each move to ensure it is within bounds and that the selected column is not full. The game should alternate turns between Player 1, represented by the character 'X', and Player 2, represented by the character 'O'. After each move, the program will display the current state of the game board, check for a win or a tie, and declare the result when the game ends. The implementation should include methods for displaying the game board and checking for a win condition (horizontal, vertical, diagonal). Upon game conclusion, the program should prompt players to decide whether to play again or exit. Proper input validation, clear prompts, and user feedback should be incorporated to enhance user experience.

Sample Paper For Above instruction

The development of an interactive Connect 4 game in Java provides a comprehensive experience in applying fundamental programming concepts such as arrays, user input handling, control structures, and method implementation. This project emphasizes the importance of intuitive game design and robust validation mechanics to ensure a seamless and engaging user experience. Building a two-player game involves not only coding for game logic but also integrating user interaction elements and ensuring correctness in move validation and win detection.

Introduction

The game of Connect 4 is a classic two-player connection game in which players alternate dropping colored discs into a vertically suspended grid. The objective is to be the first to connect four of one's own discs horizontally, vertically, or diagonally. Its straightforward rules combined with strategic gameplay make it an ideal programming project for understanding array manipulation, control flow, and game state management in Java.

Implementation and Design

Implementing a Connect 4 game requires careful structuring of the game board, user input validation, and logic for win detection. A 2D array of characters represents the game board, with additional rows and columns to simplify boundary checking. Players interact via console input, selecting columns to drop their pieces, which are then validated to prevent illegal moves, such as selecting a full column or an out-of-bounds index.

The core functional components include methods for displaying the game board, checking for wins, and resetting the game state for subsequent matches. Displaying the board involves iterating through the array and visually representing the grid with appropriate separators, facilitating clarity for players. The win detection algorithm checks for four consecutive pieces in all possible directions, ensuring thoroughness in game-ending conditions.

Method Details

The displayBoard method visually represents the current state of the grid, with row and column labels to guide user input. The checkForWin method evaluates the board for whether a player has achieved four consecutive matching characters in any direction — horizontal, vertical, or diagonal. It iterates through relevant positions in the grid and compares neighboring cells to identify winning sequences.

Additional logic manages toggling the current player after each valid move, maintaining turn order, and incrementing move counts to detect tie conditions. When the game concludes, appropriate messages are displayed, and players are prompted to decide on playing again.

Results and User Experience

The program ensures a user-friendly interface through clear prompts and feedback, confirming each move and providing updates about game status. Validation checks prevent illegal entries, enhancing robustness against user errors. After a game concludes, the option to restart or exit allows for extended engagement without program restart, mimicking real-game scenarios.

Conclusion

The Java implementation of Connect 4 demonstrates the integration of array data structures, control flow, and input validation to create an interactive and logical game. Such projects reinforce core programming skills while offering satisfying game development challenges. Proper modular design, including separate methods for display and win detection, contributes to maintainability and scalability of the codebase.
