java井字棋游戏编程代码

Java井字棋是一种基于控制台输入的井字棋游戏，可以通过编写代码来实现。下面是关于Java井字棋游戏编程代码的介绍。

首先，我们需要定义一个二维数组来表示井字棋盘：

char[][] board = new char[3][3];

然后，我们需要将井字棋盘初始化为一个空的棋盘：

for(int i=0; i<3; i++){
  for(int j=0; j<3; j++){
    board[i][j] = '-';
  }
}

接下来，我们需要实现控制台输入。可以使用Scanner类来读取用户的输入：

Scanner scanner = new Scanner(System.in);

然后，我们需要让用户输入棋子的位置。可以使用以下方式来实现：

System.out.print("Enter row and column number (example: 1 2) : ");
int row = scanner.nextInt();
int column = scanner.nextInt();

接着，我们需要根据用户输入的位置来更新井字棋盘。可以使用以下方法来实现：

board[row-1][column-1] = currentPlayer;

在更新棋盘后，我们需要检查胜负情况。可以使用以下方法来实现：

public boolean checkWinner(char[][] board, char currentPlayer){
  for(int i=0; i<3; i++){
    if(board[i][0] == currentPlayer && board[i][1] == currentPlayer && board[i][2] == currentPlayer){
      return true;
    }
    if(board[0][i] == currentPlayer && board[1][i] == currentPlayer && board[2][i] == currentPlayer){
      return true;
    }
  }
  if(board[0][0] == currentPlayer && board[1][1] == currentPlayer && board[2][2] == currentPlayer){
    return true;
  }
  if(board[0][2] == currentPlayer && board[1][1] == currentPlayer && board[2][0] == currentPlayer){
    return true;
  }
  return false;
}

最后，我们需要交替切换玩家。可以使用以下方式来实现：

if(currentPlayer == 'X'){
  currentPlayer = 'O';
}else{
  currentPlayer = 'X';
}

以上就是Java井字棋游戏编程代码的基本实现。完整代码请见下方：

import java.util.Scanner;

public class TicTacToe {
  public static void main(String[] args) {
    char[][] board = new char[3][3];
    char currentPlayer = 'X';
    Scanner scanner = new Scanner(System.in);

    for(int i=0; i<3; i++){
      for(int j=0; j<3; j++){
        board[i][j] = '-';
      }
    }

    printBoard(board);

    while(true){
      System.out.print("Enter row and column number (example: 1 2) : ");
      int row = scanner.nextInt();
      int column = scanner.nextInt();

      board[row-1][column-1] = currentPlayer;

      printBoard(board);

      if(checkWinner(board, currentPlayer)){
        System.out.println(currentPlayer + " has won the game!");
        break;
      }

      if(isDraw(board)){
        System.out.println("It's a draw!");
        break;
      }

      if(currentPlayer == 'X'){
        currentPlayer = 'O';
      }else{
        currentPlayer = 'X';
      }
    }
  }

  public static void printBoard(char[][] board){
    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();
      System.out.println("-------------");
    }
  }

  public static boolean checkWinner(char[][] board, char currentPlayer){
    for(int i=0; i<3; i++){
      if(board[i][0] == currentPlayer && board[i][1] == currentPlayer && board[i][2] == currentPlayer){
        return true;
      }
      if(board[0][i] == currentPlayer && board[1][i] == currentPlayer && board[2][i] == currentPlayer){
        return true;
      }
    }
    if(board[0][0] == currentPlayer && board[1][1] == currentPlayer && board[2][2] == currentPlayer){
      return true;
    }
    if(board[0][2] == currentPlayer && board[1][1] == currentPlayer && board[2][0] == currentPlayer){
      return true;
    }
    return false;
  }

  public static boolean isDraw(char[][] board){
    for(int i=0; i<3; i++){
      for(int j=0; j<3; j++){
        if(board[i][j] == '-'){
          return false;
        }
      }
    }
    return true;
  }
}
