Tic Tac Toe在Java中打印错误(Tic Tac Toe board printing incorrectly in Java)

我正在用Java创建一个tic-tac-toe游戏，我做的第一步就是制作棋盘。

由于循环，该板应该是3x3。谁能帮我吗？这是代码：

package myProject; import java.util.Scanner; public class TicTacDoe { public static int row,col; public static Scanner scan = new Scanner(System.in); public static char[][] board = new char[3][3]; public static char turn = 'X'; public static void main(String[] args) { for(int i = 0;i < 3; i++) { for(int j = 0;j < 3;j++){ board[i][j] = '_'; } PrintBoard(); } } public static void Play() { } public static void PrintBoard() { for(int i = 0;i < 3; i++) { System.out.println(); for(int j = 0;j < 3;j++) { if(j==0) System.out.println("| "); System.out.print(board[i][j] + " | "); } } } public boolean GameOver(int rMove, int cMove) { return false; } }

感谢您的时间！

I am creating a tic-tac-toe game in Java and the first step I do is make the board.

The board is supposed to be 3x3 because of the loops. Can anyone help me out? Here is the code:

package myProject; import java.util.Scanner; public class TicTacDoe { public static int row,col; public static Scanner scan = new Scanner(System.in); public static char[][] board = new char[3][3]; public static char turn = 'X'; public static void main(String[] args) { for(int i = 0;i < 3; i++) { for(int j = 0;j < 3;j++){ board[i][j] = '_'; } PrintBoard(); } } public static void Play() { } public static void PrintBoard() { for(int i = 0;i < 3; i++) { System.out.println(); for(int j = 0;j < 3;j++) { if(j==0) System.out.println("| "); System.out.print(board[i][j] + " | "); } } } public boolean GameOver(int rMove, int cMove) { return false; } }

Thank you for your time!

最满意答案

尝试这个：

import java.util.Scanner; public class TicTacToe { public static int row,col; public static Scanner scan = new Scanner(System.in); public static char[][] board = new char[3][3]; public static char turn = 'X'; public static void main(String[] args) { for(int i = 0;i < 3; i++) { for(int j = 0;j < 3;j++){ board[i][j] = '_'; } } PrintBoard(); } public static void Play() { } public static void PrintBoard() { for(int i = 0;i < 3; i++) { System.out.println(); for(int j = 0;j < 3;j++) { if(j==0) System.out.print("| "); System.out.print(board[i][j] + " | "); } } } public boolean GameOver(int rMove, int cMove) { return false; } }

将PrintBoard（）移出嵌套的for循环，并将if（j == 0）更改为System.out.print

给出输出

| _ | _ | _ | | _ | _ | _ | | _ | _ | _ |

try this:

import java.util.Scanner; public class TicTacToe { public static int row,col; public static Scanner scan = new Scanner(System.in); public static char[][] board = new char[3][3]; public static char turn = 'X'; public static void main(String[] args) { for(int i = 0;i < 3; i++) { for(int j = 0;j < 3;j++){ board[i][j] = '_'; } } PrintBoard(); } public static void Play() { } public static void PrintBoard() { for(int i = 0;i < 3; i++) { System.out.println(); for(int j = 0;j < 3;j++) { if(j==0) System.out.print("| "); System.out.print(board[i][j] + " | "); } } } public boolean GameOver(int rMove, int cMove) { return false; } }

Moves the PrintBoard() out of the nested for loop, and changed the if(j==0) to System.out.print

Gives the output

| _ | _ | _ | | _ | _ | _ | | _ | _ | _ |
