🔸 TLDR
You have 20 seconds. ⏱️
What does this Java code print?
No IDE.
No debugger.
No running the code. 👀
Just trace it like you would during a Java certification exam.
This tiny question combines:
▪️ i++ — use the value, then increment
▪️ ++i — increment first, then use the value
▪️ do-while — the body executes before the condition is checked
▪️ continue outer — jump directly to the loop condition
⏱️ Target time: 20 seconds
🔸 TAKEAWAYS
▪️ Never treat i++ and ++i as interchangeable.
▪️ With continue, check exactly where execution resumes.
▪️ In certification questions, trace variables statement by statement.
▪️ Tiny loops can test much more than loop syntax.
