在scala中使用类型定义多维数组

// 定义一个二维数组
val matrix: Array[Array[Int]] = Array.ofDim[Int](3, 3)

// 给二维数组赋值
matrix(0)(0) = 1
matrix(0)(1) = 2
matrix(0)(2) = 3
matrix(1)(0) = 4
matrix(1)(1) = 5
matrix(1)(2) = 6
matrix(2)(0) = 7
matrix(2)(1) = 8
matrix(2)(2) = 9

// 访问二维数组的值
val value = matrix(1)(2) // value = 6

// 打印二维数组
for (row <- matrix) {
  for (elem <- row) {
    print(elem + " ")
  }
  println()
}
