The answer is 0 1 2 1 2 3 2 3 4. This nested loop output pattern arises because the outer loop runs from 0 to 2, and for each outer value, the inner loop starts at that value and runs while it is less than or equal to that value plus 2, printing each inner loop variable. The sequence is built by concatenating the inner loop’s output for each outer iteration: outer=0 prints 0,1,2; outer=1 prints 1,2,3; outer=2 prints 2,3,4, resulting in the final string. On the Oracle Certified Professional Java SE 17 Developer 1Z0-829 exam, this tests your ability to trace nested loop control flow and variable scoping, a common trap being miscounting the inner loop’s termination condition or forgetting that the inner loop reinitializes each time. A reliable memory tip is to visualize the inner loop’s range as “current outer value to outer value plus two,” which directly produces the staggered, overlapping output pattern.

A
0 1 2 1 2 3 2 3 4
Why wrong: 4 is not printed because break outer occurs before printing.

Correct answer & explanation
✓
0 1 2 1 2 3 2 3
The program uses nested for loops where the outer loop runs from 0 to 2 and the inner loop runs from the outer loop's current value to that value plus 2. For each iteration, the inner loop variable is printed. This produces the sequence: outer=0 prints 0,1,2; outer=1 prints 1,2,3; outer=2 prints 2,3,4. However, after the inner loop completes for outer=2, the program prints a space (not shown) and then the loop ends, so the output is '0 1 2 1 2 3 2 3 4' — but note the last value 4 is printed, making option B correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates miscount the number of iterations or misjudge the inner loop's termination condition, often thinking the inner loop runs from 0 to i+2 instead of from i to i+2, leading to sequences like 0 1 2 0 1 2 0 1 2 or adding extra values.
Detailed technical explanation
How to think about this question
The nested loop structure demonstrates how the inner loop's starting point depends on the outer loop's current value, creating a triangular iteration pattern. In Java, the for loop initializes the inner variable to the outer value, and the condition `j <= i + 2` ensures exactly three iterations per outer loop (i, i+1, i+2). This pattern is common in algorithms that process subarrays or sliding windows, where the starting index shifts with each outer iteration.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-829 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.

What is the correct answer to this question?
The correct answer is: 0 1 2 1 2 3 2 3 — The program uses nested for loops where the outer loop runs from 0 to 2 and the inner loop runs from the outer loop's current value to that value plus 2. For each iteration, the inner loop variable is printed. This produces the sequence: outer=0 prints 0,1,2; outer=1 prints 1,2,3; outer=2 prints 2,3,4. However, after the inner loop completes for outer=2, the program prints a space (not shown) and then the loop ends, so the output is '0 1 2 1 2 3 2 3 4' — but note the last value 4 is printed, making option B correct.
