Java expression - hot express ArrayIndexOutOfBounds in If Statement

Question

Hi !
I would like to know how I can express the following correctly:
Testcode - just to show what i mean:
int[][] testArray = whatever assignments here
if (testArray[line][row] != ArrayIndexOutOfBoundsException)
.... do stuff here...
}As obvious I basically just wanna add numbers across this twodimentional array - in rows - not lines !.
And as some lines and rows can be shorter than others, eventually Ill end up with an OutOfBoundsException.
So how can I handle those inside the if statement ? What is the correct expression to avoid those?
As the current expression doesent work.
As obviously those slots are NOT null but literally non existent slots, that must be checked for before adding the int inside.
Thanks for help !

Answer 1

"sort on the array" ?
yeah actually where can I look up the methods for arrays ?
anyway, I left it a bit and eventually came back to it:
Now I have it fixed to calculate the columns for any 2D array
Cheers for the good comments though !
zeile = line
spalte = column
    int spaltenMax = 0;
    for (int zeile = 0; zeile < data.length; zeile++)
         if (spaltenMax < data[zeile].length)
              spaltenMax = data[zeile].length;              
    System.out.println("There are " + spaltenMax +" columns" );
    for (int spalte = 0; spalte < spaltenMax; spalte++)
        for (int zeile = 0; zeile < data.length; zeile++)
                  int zeilenL = data[zeile].length;
                  if (zeilenL-1 >= spalte)
                       rowSum += data[zeile][spalte];
        System.out.println("For column " +(spalte+1)  + " the sum is: " +rowSum );
        rowSum = 0;
