get()
returns a String
in this case and then you call add()
on the String
returned by get()
. The String
class does not have an add()
method, hence the undefined for type String
error. I believe you simply wanted:
indirizzi.add(ind);
Which will add the user input to the List
.
If you want to add at a specific index then use the set()
method:
indirizzi.set(i, ind);
Which will set ind
to the i
'th index of indirizzi
yeah but I wanted to add the string in that i position of the arraylist

@user10610048add()
adds the element to the end of the list so if theList
is empty, then it will already be setting the elements to theith
position. If not then check my edit about theset()
method
