scala 2 dimensional array
提问by Wins
This may sound easy, but I just can't get it right.
这听起来可能很简单，但我就是做对了。
How to create a 2 dimensional array with size 100 by 60 in Scala? Supposed I have class called Abcd and I want to create a 2 dimensional array of Abcd. I tried with the following code but doesn't work.
如何在 Scala 中创建大小为 100 x 60 的二维数组？假设我有一个名为 Abcd 的类，我想创建一个 Abcd 的二维数组。我尝试使用以下代码但不起作用。
var myArray = new Array[Array[Abcd]](100,60)
It complains "too many arguments for constructor Array"
它抱怨“构造函数数组的参数太多”

Or if you prefer to have your array start with ABCD's instead of nulls
或者，如果您希望数组以 ABCD 而不是空值开头
Array.fill[ABCD](100,6) { new ABCD }
or if the ABCD vary in some regular way by position
或者如果 ABCD 因位置而有规律地变化
Array.tabulate[ABCD](100,6) { (i,j) => new ABCD(i,j) }

I know this question is answered but one problem I ran into was that @alexwriteshere's solution and @Chick's solution was only good if you wanted a matrix.
我知道这个问题已得到解答，但我遇到的一个问题是 @alexwriteshere 的解决方案和 @Chick 的解决方案仅在您需要矩阵时才有效。
To be able to create a two-dimensional array with (if viewed as first number of rows then number of columns), do something like this:
为了能够创建一个二维数组（如果被视为第一个行数然后是列数），请执行以下操作：
val array = Array.ofDim[Array[Char]](2)
array(0) = Array.ofDim[Char](10)
array(1) = Array.ofDim[Char](20)
