array.size() cannot be resolved

Question

I got this code

public void displayText(){
    int resourceId = getResources().getIdentifier(chosenArrayName, "array", getPackageName());
    String[] array = getResources().getStringArray(resourceId);
    int arraySize = array.size();
    for(int i = 0; i < arraySize; i++) {
        textView.append(array[i]);}

    }

From Android how to print a array in text view or anything

The arraySize = array.size(); cannot be resolved. Anyone help me to point out why?

`resourceId` is `int` type. how come you expect an integer to have a `size()` function — devgun, Dec 18 '17 at 08:51

@NagyVilmos I understand, but why is it using .size in the answer of this link. https://stackoverflow.com/questions/9668041/android-how-to-print-a-array-in-text-view-or-anything — Anthony, Dec 18 '17 at 09:01
For those downvoting, Please explain why so that we can learn. — Anthony, Dec 18 '17 at 09:06
your array is a int array => int[] so you must use .length property. if it was a Collection, then you could use size() method. — Utkan Ozyurek, Dec 18 '17 at 09:35
@NagyVilmos Thanks Nagy, Can anyone just delete/downvote/reanswer the question since i had search the forum and it is appearing a lot in the search, but is a wrong answer. — Anthony, Dec 19 '17 at 01:01
@Anthony I've already commented there that answer could be misleading, or wrong. — Nagy Vilmos, Dec 19 '17 at 09:25

You cannot call size() method in int. Try this :

public void displayText(){
    int resourceId = getResources().getIdentifier(chosenArrayName, "array", getPackageName());
    String[] array = getResources().getStringArray(resourceId);
    int arraySize = array.length;
    for(int i = 0; i < arraySize; i++) {
        textView.append(array[i]);}
}
