This 1Z0-829 practice question tests your understanding of controlling program flow. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
What is the output of the following code? int i=5; do { System.out.print(i); i--; } while(i>0);
54321
The loop prints each number from 5 down to 1.
Compilation error
Why wrong: The code is syntactically correct.
543210
Why wrong: It does not print 0 because the condition is checked after decrement.
5432
Why wrong: It also prints 1.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
54321
The do-while loop executes the body first, then checks the condition. Starting with i=5, it prints 5, decrements to 4, checks condition (4>0 true), continues. It prints 5,4,3,2,1. When i becomes 0, the condition fails. So output is '54321'. Option A is correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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 1Z0-829 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.
