使用 5x5 数组创建 Java 递增字母表网格

Question

我需要重新创建的网格如下所示

 ABCDE
T.....F
S.....G
R.....H
Q.....I
P.....J
 ONMLK

我现在的网格是这样的

 ABCDE
0.....0
1.....1
2.....2
3.....3
4.....4
 ONMLK

我创建网格的代码

// * Method * Creating the maze grid
public static void createMazeGrid(){
    // First section of Maze Grid
    System.out.print("  ");
    for(char alphabet = 'A'; alphabet < 'F'; alphabet++)
        System.out.print(alphabet);
    System.out.println();

    // Middle section of Maze Grid
    // *TRY TO FIGURE OUT ALPHABET GRID*
    for(int i = 0; i < maze.length; i++) {
        System.out.print(" ");
        for (int j = 0; j < maze[i].length; j++) {
            maze[i][j] = ".";
            if (j == 0)
                System.out.print(i + maze[i][j]);
            else if (j == maze[i].length - 1)
                System.out.print(maze[i][j] + i);
            else
                System.out.print(maze[i][j]);
        }
        System.out.println();
    }

    // Last section of Maze Grid
    System.out.print("  ");
    for(char alphabet = 'O'; alphabet > 'J'; alphabet--)
        System.out.print(alphabet);
    System.out.println();
}

我已经在public class中声明了这些变量，而不是我的主要方法。我将如何实现这一目标？我尝试将地图中间部分的 int 更改为 char，就像我的顶部和底部部分一样，但它只是切掉了地图的中间部分。

public static int numRows = 5;

public static int numCols = 5;

public static String[][] maze = new String[numRows][numCols];

完成代码的一种简单方法是在已有输出的地方使用字符。

public class Maze {
    public static int numRows = 5;
    public static int numCols = 5;
    public static String[][] maze = new String[numRows][numCols];
// * Method * Creating the maze grid
public static void createMazeGrid(){
    // First section of Maze Grid
    System.out.print("  ");
    for(char alphabet = 'A'; alphabet < 'F'; alphabet++)
        System.out.print(alphabet);
    System.out.println();

    // Middle section of Maze Grid
    // *TRY TO FIGURE OUT ALPHABET GRID*
    for(int i = 0; i < maze.length; i++) {
        System.out.print(" ");
        for (int j = 0; j < maze[i].length; j++) {
            maze[i][j] = ".";
            if (j == 0)
                System.out.print((char)('T' - i) + maze[i][j]); // left side
            else if (j == maze[i].length - 1)
                System.out.print(maze[i][j] + (char)('F' + i)); // right side
            else
                System.out.print(maze[i][j]);
        }
        System.out.println();
    }

    // Last section of Maze Grid
    System.out.print("  ");
    for(char alphabet = 'O'; alphabet > 'J'; alphabet--)
        System.out.print(alphabet);
    System.out.println();
}
public static void main(String[] args) { createMazeGrid(); }
}

现在让我们测试一下：

$ java Maze.java
  ABCDE
 T.....F
 S.....G
 R.....H
 Q.....I
 P.....J
  ONMLK

看起来不错。 :-)
