Question

Im triying to make a list which should look like this
Pages = [“Page 1”, “Page 2” … “Page 48”]

and im using this, Is there anything wrong with the following lines?

String[] Pages = {};
    int i = 0;
    for (; i < 47; i++) {
        String p = Integer.toString(i+1);
        Pages[i] = ("Page " + p);
    }

it keeps giving me a arrayIndexOutOfBoundsException

Answer 1

As I mentioned in my comment,

The ArrayIndexOutOfBoundsException is caused by the fact that Pages is declared to be { }, and therefore has no indexable elements — it has a length of 0.

The exception is being thrown when evaluating Pages[i], not when doing "Page " + p. To correct, try instead String[] Pages = new String[47]; 🙂

OR, as Ash mentioned in the comments, do you want a List<String> instead?

final List<String> pages = new ArrayList<String>(47);
for (int i = 1; i <= 47; ++i) {
  pages.add("Page " + i);
}
