null in 2 dimensional array problem

I have a problem on checking process to determine validity.

Code is something like :

Code:

---

        private boolean isInOtherAField() {
                  try {
                        qfield.setQuery("SELECT afield, acode FROM test WHERE afield = '" + txAField.getText().toString().trim() + "';");
                } catch (SQLException e) {
                        e.printStackTrace();
                };
                if (!(qfield.getValueAt(0, 0).toString().trim()).equals(txAField.getText().toString().trim())){
                        return true;
                } else {
                        return false;
                }
        }

---

qfield is tablemodel extended from abstracttablemodel.
Then in my main code I call isInOtherAField() and determine what to do on true and false return value.
When the query returns a row whether it's true or false, it works fine.
However then there's problem when the query returns empty result (in case of a new field code), which gives me :
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0 >= 0

is there any way to handle this null 2-dimensional array ?

Thanks in advance,

Not sure what you are asking but generally you would check the length of an array before trying to access an element in the array.

I skipped checking array length, now doing the length checking first and seems fine

If there's no more post then it's solved


Thanks,

Sorry about that, with our new s/w we cannot do that as far as I know. Just by editing the thread we can do that. Sorry, since I get use of to do that I think others will do the same.

Just have this checked and yes, it was answered and problem solved, but how to do that SOLVED mark that you said ?

So far I have most if not all are solved thanks to the ppl here.
Just let me know how-to and I'll mark it solved.

Thanks,
