Setting Up the Game Board
To begin coding our Tic-Tac-Toe game, we'll start by creating a 3x3 game board using a 2D array. This array will represent the cells on the game board where players can place their marks. We'll also initialize the current player, which starts as 'X'. This setup is crucial as it defines the playing field and the initial state of the game.
```java
// Create a 3x3 game board using a 2D array
private static char[][] board = new char[3][3];
private static char currentPlayer = 'X';
```
The Main Game Loop
The heart of the game lies in a loop that keeps the game running until it's over. Within this loop, players take turns making moves, and the game checks for a win or draw condition. This loop acts as the core engine of the game, ensuring that players can continue to interact with the board until a result is achieved.
```java
boolean gameInProgress = true;
while (gameInProgress) {
// Display the current game board
printBoard();
// Get the player's move (row and column)
int[] move = getPlayerMove();
int row = move[0];
int col = move[1];
if (isValidMove(row, col)) {
board[row][col] = currentPlayer;
gameInProgress = !isGameOver(row, col);
currentPlayer = (currentPlayer == 'X') ? 'O' : 'X';
} else {
System.out.println("Invalid move. Try again.");
}
}
```
Game Board Initialization
Before the game begins, it's essential to initialize the game board with empty cells using a nested loop. Initializing the board ensures that players start with a clean slate, and no previous game data carries over. It sets the stage for a fair and fresh game.
```java
private static void initializeBoard() {
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
board[i][j] = ' ';
}
}
}
```
Displaying the Game Board
The printBoard method is responsible for displaying the current state of the game board after every move. This display is critical for players to see the progress of the game, allowing them to make informed decisions for their next move. It ensures transparency and keeps the players engaged throughout the game.
```java
private static void printBoard() {
System.out.println("-------------");
for (int i = 0; i < 3; i++) {
System.out.print("| ");
for (int j = 0; j < 3; j++) {
System.out.print(board[i][j] + " | ");
}
System.out.println("\n-------------");
}
}
```
Getting Player Input
We need a method to get the player's move, including the row and column where they want to place their mark. Getting input from the players is a fundamental aspect of any interactive game. It enables players to participate actively and make strategic decisions, driving the game forward.
```java
private static int[] getPlayerMove() {
Scanner scanner = new Scanner(System.in);
int[] move = new int[2];
System.out.println("Player " + currentPlayer + ", enter your move (row and column): ");
move[0] = scanner.nextInt();
move[1] = scanner.nextInt();
return move;
}
```
Validating Moves
To ensure that a move is valid, we check whether the selected cell is within the board boundaries and is not already occupied. Validating moves is essential to maintain the integrity of the game. It prevents players from making illegal moves and ensures that the game progresses according to the rules.
```java
private static boolean isValidMove(int row, int col) {
return row >= 0 && row < 3 && col >= 0 && col < 3 && board[row][col] == ' ';
}
```
Checking Game Over Conditions
We need to check if the game is over, either due to a win by a player or a draw. This step is crucial for determining when the game should conclude. It involves evaluating the game state to see if a player has achieved a winning condition or if the board is full, resulting in a draw.
```java
private static boolean isGameOver(int row, int col) {
return isWin(row, col) || isBoardFull();
}
```
Determining the Winner
Finally, we determine the winner based on the game's rules. Identifying the winner is the ultimate goal of the game. This step involves analyzing the current state of the board and checking for patterns or combinations that indicate a player's victory. It's the culmination of the game and announces the triumphant player.
```java
private static char getWinner() {
if (isWin(0, 0) || isWin(1, 1) || isWin(2, 2) || isWin(0, 2) || isWin(2, 0)) {
return currentPlayer;
} else {
return ' ';
}
}
```
