Assigning part of an array in Java

I want to fill in part of an array with the values of another array. Is there anyway I can do this without looping?

eg

int [] [] ArrayToFillIn = new int [3] [3]
int [] FillingArray = {1, 2};

for (int i = 1; i < 3; i++)
{
    ArrayToFillIn [i-1] [2] = FillingArray [i - 1];
}

in R it would be like:

ArrayToFillIn [c(1:2),3] = FillingArray []

(considering that R does not start from 0)

Thanks!

Sure. Without a loop it would be

ArrayToFillIn [0] [2] = FillingArray [0];
ArrayToFillIn [1] [2] = FillingArray [1];

What with this initialization:

int [] FillingArray = {1, 2};
int [][] ArrayToFillIn = new int[][]{{0, 0, FillingArray[0]}, {0, 0, FillingArray[1]}, {}};
