Question

Don't worry about what this class does. We're asking about Java language elements. Select the local variables in this class

01: public class StrCharCounter
02: {
03:
04: private ArrayList < String > store = new ArrayList<>();   
05: private int size = 0;
06:
07: public boolean add(String sToAdd)
08: {
09: size++;
10: if (!store.contains(sToAdd))
11: return store.add(sToAdd);
12: else
13: return false;
14: }
15:
16: public int calcTotalLength()
17: {
18: int cnt = 0;
19: for (int i = 0; i < size; i++)
20: {
21: cnt += store.get(i).length();
22: }
23: return cnt;
24: }
25: }
