Java错误：线程“main”中的异常java.lang.ArrayIndexOutOfBoundsException：6

I am trying to write a simple part of my code in the process to create a Connect 4 game. I am trying to create and display a 6 by 7 board as such where I can eventually drop X's and O's:

I keep getting an error: Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 6

我一直收到错误:线程“main”中的异常java.lang.ArrayIndexOutOfBoundsException:6

public static void printConnect4Board(){
final int WIDTH = 6;
final int HEIGHT = 7;
int [] [] connect4Board = new int [WIDTH][HEIGHT];
Scanner input = new Scanner(System.in);
for(int w = 0; w < connect4Board.length; w++){
   for(int h = 0; h < connect4Board[w].length; h++){
       System.out.println(connect4Board[w][h] + "|");
    }
    System.out.println();
}

}

Any help will be appreciated. Thanks.

任何帮助将不胜感激。谢谢。

Swap your indexes and change from println to print:

交换索引并从println更改为print:

public static void printConnect4Board(){
    final int WIDTH = 6;
    final int HEIGHT = 7;
    int [] [] connect4Board = new int [WIDTH][HEIGHT];
    Scanner input = new Scanner(System.in);
    for(int h = 0; h < HEIGHT; h++){
        System.out.print("|");
        for(int w = 0; w < WIDTH; w++){
            System.out.print("|");
        }
        System.out.println();
    }
}
