Matécsa Andrea :
I would like to initialize an Array of pairs but my way is not fully correct. Here how I first wrote it:
Pair<String, Integer>[] pair = new Pair[5];
It is accepted and it works but there is still the following warning:
"Unchecked assignment:
'android.util.Pair[]'to'android.util.Pair<Java.lang.String, Java.lang.Integer>[]'...
I already tried to do like this:
Pair<String, Integer>[] pair = new Pair<String, Integer>[5];
but it doesn't work.
MC Emperor :
It is because of the nature of generics.
My suggestion is to drop the idea of using arrays directly, and use a List<Pair<String, Integer>> instead. Under the hood, it uses an array anyway, but a List is more flexible.
List<Pair<String, Integer>> list = new ArrayList<Pair<String, Integer>>();
// You don't have to know its size on creation, it may resize dynamically
or shorter:
List<Pair<String, Integer>> list = new ArrayList<>();
You can then retrieve its elements using list.get(index) whereas you would use list[index] with an array.
