Dynamic two dimensional Arrays

[copthesaint]

So I know what increasing the bound of a dynamic array, you want to create a temperary array with the larger bound and copy the previous array to it. eg.

Java:

int boundSize = 1;          int[] oldArray = new int [boundSize];          oldArray [boundSize-1] = 0;          boundSize = boundSize+ 1;          int[] newArray= new int[boundSize];          System.arraycopy(oldArray, 0, newArray, 0, oldArray.length);          oldArray= newArray;          oldArray [boundSize-1] = 1;          for (int i = 0; i < oldArray.length; i++){             System.out.println (oldArray [i]);          }

However I am just wondering how I would go about doing this with a [][] dimensional array.

Mostly in the same way. If you have int[][] arr; wouldn't arr[x] return an int[] type?

Also, the typical strategy for resizing arrays is to double their length (instead of doing +1), but that choice depends on the behaviour of your program.

Yep, I realized like 10 min after, when I ate something, That arr[x] would return an array... I kinda just face-palmed myself.. anyways thanks
