Obj In array as int

[mnml]

Hi,
I am trying to make a if loop using a Int value contained in an Array
'array2D[a][a]'

if(array2D[a][a]==0)
dosomething();

I would like to know how I can define the content as an Integer in
that case;
The error message:

../myDisplay.java:52: incomparable types: java.lang.Object and int
if(array2D[a][a]==0)
^

Thanks

Are you trying to make a 2D array of Integer objects
Integer [][] array2D = new Integer[a];
or 2D array of int (primitive data type)
int[][] array2D = new int[a];

If is NOT a loop...

To the OP: Here's where an SSCCE
<http://www.physci.org/codes/sscce.html>
can be so very useful.

Notice that GArlington's question can only be answered by reference to the
code that you /didn't/ post.

An Integer or int array would've worked.

Another hint - the error message told you what was wrong. You were comparing
an Object to an int. What would have been comparable, if not Object to int?
