RECALL
kbd.next();
String word = kbd.next();
int wordLen = word.length();
for (int j = 0; j < wordLen; j += 2) {
System.out.print(word.charAt(j));
}Assume that kbd is our usual Scanner beastie getting keyboard input.
If a user enters good morning and hits Enter, what will the above code print out?
RECALL
int i = 0;
boolean done = false;
int n = -1;
while (i <= nums.size() && !done) {
n = nums.get(i);
if (n < 3) {
done = true;
}
i += 1;
}Assume the ArrayList<Integer> nums contains these integers:
| 5 | 3 | 7 | 2 | 17 |
|---|
What values do i and n have when the loop completes?
Is there a potential bug in this code? Where?
