最简单的方法是将2d int数组转换为2d double [英] Shortest way to cast a 2d int array into 2d double

问题描述

我有一个方法，它只能获得 int [] [] 的 double [] [] $ c>，是有一个简单的方法，这样做在java中，简单的如：

  int [] [] iArray = {
 {1，2，}，
 {5，6，} 
}; 
 double [] [] dArray =（double [] []）iArray; ???不幸的是，投射你的数组的唯一方法是迭代（iterate），你可以使用这个方法来创建一个新的数组。通过每个元素并一个接一个地转换，同时在新的 double [] [] 数组中重新插入。 
 
 
 
没有捷径。
 
I have a method which only gets double[][] to which I would like to pass int[][], is there a short way of doing this in java, something as simple as:
int [][] iArray = {
          { 1, 2, },
          { 5, 6, }
        };
double [][] dArray = (double[][]) iArray ; ???

解决方案
Unfortunately the only way to cast your array is to iterate through each element and cast them one by one while re-inserting in your new double[][] array. 

There is no shortcut.
