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