Android: Storing int and String values in one multidimensional array

Question

is it possible to store different values into a multidimensional array such as int's and String's?

String[][] mainArray= new String[2][2];

    mainArray[0][0] = 1;
    mainArray[0][1] = "Name1";
    mainArray[1][0] = 2;
    mainArray[1][1] = "Name2";

this obviously doesn't work because 1 and 2 are not String values

yes you can store try this

        String[][] mainArray= new String[2][2];

        mainArray[0][0] = String.valueOf(1);
        mainArray[0][1] = "Name1";
        mainArray[1][0] = String.valueOf(2);
        mainArray[1][1] = "Name2";

The values of 1 and 2 still appear to be strings in this code. When I add the two together, i get the result of 12 ("1"+"2") and not 3 (1+2)

You can create an Object array, and save Integers, which is the boxing of the primitive int.

Object[][] arr = new Object[2][2];
arr[0][0] = "hello";
arr[0][1] = Integer.valueOf(1);
arr[1][0] = Integer.valueOf(2);
arr[1][1] = "world";

My fault for not pointing this out earlier. I need to be able to sort the array. From what I understand, Objects are not sortable.

Here is the solution

Object[][] arr=new Object[anysize][]; and you can do like this
arr[0][0]=1;
arr[1][0]="hello";

But while accessing this array you should also do this using Object only.Else there may be ClassCastException.
