I am trying to append an item to the empty list which I created in java by using

String[] list_of_days = {};

How can I append the items, e.g., numbers from 1 to 10, in this list, like I used to do in Python using append function.

list_of_numbers.append(variable)??`enter code here`

Arrays are fixed-size. Use a `List` – bradimus Jun 21 '17 at 14:43

That's an array, it's not resizable. You want a `List` instead. – Blorgbeard Jun 21 '17 at 14:43
If you know the array size from the beginning, then https://stackoverflow.com/a/36438433/4852017 seems very useful. If not, then an ArrayList might be more helpful as you can just call arrList.add() – ZeldaZach Jun 21 '17 at 14:46
It should be better to use StringBuilder class and append the values – user1918566 Jun 21 '17 at 22:04
