    Default How to convert an array of integer to generic type?

    I have an array,
    private T[] elements;
    . I would like to do this ideally:

    if(elements[index] == null){
        elements[index] =  0;
    }
    elements[index] = elements[index] + 1;

    But I get the error of "cannot cast from int to T." How can I check my array for a null space and change it to zero if null is encountered (and then increment the 0 to 1)?

    What type is T? It may not even make sense to cast an int to T, for example if elements is meant to hold String objects.

    elements[index] = 0;
    }
    elements[index] = elements[index] + 1;


    But I get the error of "cannot cast from int to T." How can I check my array for a null space and change it to zero if null is encountered (and then increment the 0 to 1)?
    Why set it to zero in the first place then? why not just say if i of elements == null then i of e = 1;
