java逆时针打印矩阵

以下是Java代码，逆时针打印一个矩阵：

public static void printMatrixInReverse(int[][] matrix) {
    if (matrix == null || matrix.length == 0 || matrix[0].length == 0)
        return;
    
    int rows = matrix.length;
    int cols = matrix[0].length;
    int left = 0, top = 0, right = cols - 1, bottom = rows - 1;
    
    while (left <= right && top <= bottom) {
        for (int i = top; i <= bottom; i++) {
            System.out.print(matrix[i][left] + " ");
        }
        left++;

        for (int j = left; j <= right; j++) {
            System.out.print(matrix[bottom][j] + " ");
        }
        bottom--;

        if (left <= right && top <= bottom) {
            for (int i = bottom; i >= top; i--) {
                System.out.print(matrix[i][right] + " ");
            }
            right--;
        }

        if (left <= right && top <= bottom) {
            for (int j = right; j >= left; j--) {
                System.out.print(matrix[top][j] + " ");
            }
            top++;
        }
    }
}

例如，给定以下矩阵：

int[][] matrix = {
    {1, 2, 3},
    {4, 5, 6},
    {7, 8, 9}
};

打印结果将为：9 8 7 6 5 4 3 2 1
