Which of the following is a correct replacement for /∗ more code ∗/?
(A) for (Coin c : coins) {
c = coins.get(i);
total += c.getValue(); }
(B) for (Coin c : coins) {
Coin value = c.getValue();
total += value; }
(C) for (Coin c : coins) {
Coin c = coins.get(i);
total += c.getValue(); }
(D) for (Coin c : coins) {
total += coins.getValue(); }
(E) for (Coin c : coins) {
total += c.getValue(); }
27. Two coins are said to match each other if they have the same name or the same value. You may assume that coins with the same name have the same value and coins with the same value have the same name. A boolean method find is added to the Purse class:
/∗∗ @return true if the purse has a coin that matches aCoin,
∗ false otherwise
∗/
public boolean find(Coin aCoin) {
for (Coin c : coins)
