一、多维数组

### --- 多维数组

~~~     通过Array的ofDim方法来定义一个多维的数组，多少行，多少列，都是自己说了算。

### --- 多维数组示例

~~~     # 创建一个3行4列的二维数组
val dim = Array.ofDim[Double](3,4)
dim(1)(1) = 11.11
for (i <- 0 to 2; j <- 0 to 3) {
    print(dim(i)(j) + " ")
    if (j == 3) println()
}

### --- 编程代码

package yanqi.cn.part03

object MultipleArrayDemo {
  def main(args: Array[String]): Unit = {
    //定义一个3行4列的二维数组
    val dim = Array.ofDim[Double](3, 4)
    dim(1)(1) = 12.5
    for (i <- 0 to 2; j <- 0 to 3){
      print(dim(i)(j)+"   ")
      if(j==3) println()
    }
  }
}
