A method uses an enhanced for loop to iterate over a list of strings and prints each string. The code is: ```java List list = List.of("A", "B", "C"); for (String s : list) { if (s.equals("B")) { break; } System.out.print(s); } ``` What is the result?

The code throws a ConcurrentModificationException.

A method uses an enhanced for loop to iterate over a list of strings and prints each string. The code is:

```java List<String> list = List.of("A", "B", "C");

for (String s : list) {
    if (s.equals("B")) {

break;

System.out.print(s);

```

What is the result?

⚠ Common exam trap

Many exam-takers think the break statement causes a ConcurrentModificationException or that it prints "AB" because they forget that break exits the loop before executing the print statement for the matched element.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The enhanced for loop iterates over the list, and when it encounters the string "B", the break statement immediately exits the loop. Therefore, only "A" is printed before the loop terminates. Option C is correct because the output is just "A".

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The code throws a ConcurrentModificationException.
Why it's wrong here
The list is not modified during iteration.
✗
ABC
Why it's wrong here
Break prevents printing B and C.
✓
A
Why this is correct
Prints A, then breaks at B.
✗
AB
Why it's wrong here
Break occurs before printing B.
