Dynamic variables

[McGowan]

Hi, I am trying to loop through 81 text boxes each time reading the
text from the box and placing it in a 2d array.

My code below shows it doing just the first line so only 9 text boxes

private void jButton1_actionPerformed(ActionEvent e) {
int userAnswer [][] = new int [9][9];

for (int i = 0; i < 9; i++) {
try {
userAnswer [0] = Integer.valueOf(A1.getText());
} catch (NumberFormatException nf) {
userAnswer[0] = 0;
}
System.out.println(i + " " + userAnswer[0]);
}
}

Where it says A1 I want it to change automatically to A2, A3, A4 and
so on on each iteration of the loop increasing by 1 all the way to 9.

Any ideas?

Thanks,
OIiver

Put your A* in an array of their own (A would offer itself as a name,
were it not that by convention, names of variables start with a lower
case letters, and such short names are very cryptic), and use the array
index.

Is this by any chance a Sudoku related project

Like Hendrik suggests, you should use an array of textAreas, rather
than 81 seperate instances. That way you can create them and add them
to your panel in a loop as well.
