Convert vector[][] into int[][]

Question

I am using this code:
for(i=0;i < row; i++) {
                    for(j=0; j < column; j++) {
                         numbersIntArray[i][j] = ((Integer)numbersVector[i][j]).intValue();
               }to try to convert a 2dimensional vector to a 2dimensional int array, but i'm getting this error:
found   : java.util.Vector
required: java.lang.Integer
                         numbersIntArray[i][j] = ((Integer)numbersVector[i][j]).intValue();any ideas?

Answer 1

* Where array.txt is a file containing the following numbers,
* separated by spaces.
* 1 2 3 4 5
* 6 7 8 9
* 11 12 13 14 15
