我正在用面向对象的概念用java编写一个最终的tic-tac-toe，我正在尝试制作电路板并正确地打印出来。我做了一个bigboard类，它有9个小板，每个小板由9个盒子组成，每个盒子都有一个索引。当我试着打印的时候，我得到了这个。

| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |
| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |
| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |

| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |
| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |
| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |

| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |
| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |
| 0 | 1 | 2 |
| 3 | 4 | 5 |
| 6 | 7 | 8 |

而不是这个

| 0 | 1 | 2 | | 0 | 1 | 2 | | 0 | 1 | 2 | 
| 3 | 4 | 5 | | 3 | 4 | 5 | | 3 | 4 | 5 |
| 6 | 7 | 8 | | 6 | 7 | 8 | | 6 | 7 | 8 |

| 0 | 1 | 2 | | 0 | 1 | 2 | | 0 | 1 | 2 | 
| 3 | 4 | 5 | | 3 | 4 | 5 | | 3 | 4 | 5 |
| 6 | 7 | 8 | | 6 | 7 | 8 | | 6 | 7 | 8 |

| 0 | 1 | 2 | | 0 | 1 | 2 | | 0 | 1 | 2 | 
| 3 | 4 | 5 | | 3 | 4 | 5 | | 3 | 4 | 5 |
| 6 | 7 | 8 | | 6 | 7 | 8 | | 6 | 7 | 8 |

大板类打印方法

void print () {
        System.out.println("printing the " + this.name  + " info....");

        for (int i = 0; i < boards.length; i++) {
            if (i!=0 && i%boardColSize == 0) 
                System.out.println();
            boards [i].print();
        }
        System.out.println("");
    }
}

小板类打印方法

void print () {
        for (int i = 0; i < boxes.length; i++) {
            if (i!=0 && i%boardColSize == 0) 
                System.out.println();
            boxes [i].print();
        }
        System.out.println("");

盒类打印方法

void print() {
        if (Integer.valueOf(placeHolder) == 2 || Integer.valueOf(placeHolder) == 5 || Integer.valueOf(placeHolder) == 8)
            System.out.print("| "+placeHolder + " |");
        else
            System.out.print("| "+ placeHolder + " ");
    }

}

如何将小板格式化为3x3网格？
