Consider the following method that is intended to test if all the strings in the arraylist start with an uppercase letter:

public static boolean capitalized(arraylist a) {
/* missing code */
}
which of the following could replace /* missing code */ so that the method works as intended?

i.

for (string s: a) {
if (s.(0) ! = s. charat(0)) {
return true;
}
}
return false;

ii.

for (string s: a) {
if (s.(0) ! = s. charat(0)) {
return false;
}
}
return true;

iii.

int flag = 1;
for (string s: a) {
if (s.(0) ! = s. charat(0)) {
flag = 0;
}
}
return (flag == 1);
ii only
iii only
i, ii and iii
i only
ii and iii
