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: }

? StrCharCounter ? store ? size ? add ? calcTotalLength ? cnt ? i ? There are no local variables
