Quick Answer
The answer is 3. This result comes from the for loop sum of integers in Java, where the loop initializes i to 0 and runs while i is less than 3, incrementing i by 1 each iteration. Inside the loop, the statement sum = sum + i accumulates the values: first 0+0=0, then 0+1=1, and finally 1+2=3, so after the loop ends, sum holds 3. On the Oracle Java Foundations 1Z0-811 exam, this tests your understanding of loop iteration and variable accumulation, a common pattern for calculating totals. A frequent trap is forgetting that the loop starts at 0, not 1, which would change the sum; here, starting at 0 adds nothing to the first pass. Memory tip: for a loop that runs n times starting from 0, the sum of integers from 0 to n-1 equals n*(n-1)/2, so for n=3, that’s 3*2/2 = 3.
This 1Z0-811 practice question tests your understanding of control flow and loops. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Refer to the exhibit.
int sum = 0;
for (int i = 1; i <= 10; i++) {
if (i % 3 == 0) {
break;
}
sum += i;
}
System.out.println(sum);What is the value of sum printed?
Refer to the exhibit.
int sum = 0;
for (int i = 1; i <= 10; i++) {
if (i % 3 == 0) {
break;
}
sum += i;
}
System.out.println(sum);6
Why wrong: Would be sum if break at i=4.
0
Why wrong: Not correct.
3
Correct: sum of 1+2=3 before break.
1
Why wrong: Only first iteration.

Correct answer & explanation
3
The correct answer is C because the loop iterates from i=0 to i<3, incrementing i by 1 each time. Inside the loop, sum is updated as sum = sum + i, so sum becomes 0+0=0, then 0+1=1, then 1+2=3. After the loop ends, sum is 3.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Oracle often tests the off-by-one error where candidates mistakenly include the final value (i=3) or start counting from 1 instead of 0, leading to incorrect sums like 6 or 1.
Detailed technical explanation
The for loop in Java uses an initializer, condition, and update expression. The condition i<3 is evaluated before each iteration; when i becomes 3, the condition is false and the loop terminates. The sum variable is updated by adding the current i, which takes values 0, 1, and 2. This is a classic example of how loop bounds and initial values affect accumulated results, often used in array summation or index-based iteration.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
