I have a question in the html and css of this code How to replace all values of a given table in MYSQL at once?

score 1 · Accepted Answer

The problem is within for :

for (int i = 0; i < vet.length; i++) {
    list.add(Integer.parseInt(vet[1]));
}

Instead of getting the position of the array indicated by the loop ( i ), you are always taking position 1 ( vet[1] ).

When the array has only one element, the only valid position is zero (arrays start with zero index), and when trying to access position 1, the code throws an exception.

Just swap vet[1] with vet[i] :

for (int i = 0; i < vet.length; i++) {
    list.add(Integer.parseInt(vet[i]));
}
