Simulate the real Oracle Certified Professional Java SE 17 Developer 1Z0-829 exam with full-length timed sessions. Questions drawn proportionally from all 8 official blueprint domains — the same mix you'll face on test day.
Simulate real exam conditions
For the most realistic 1Z0-829 simulation, start a 60 or 120-question session, put away all notes, set a timer matching the real exam duration (90 minutes), and commit to each answer before moving forward. This trains the time management and decision-making skills the real exam tests.
This free 1Z0-829 mock exam uses the same question distribution as the real Oracle Certified Professional Java SE 17 Developer 1Z0-829 exam. Each session draws questions proportionally from all 8 official blueprint domains published by Oracle, so the topic mix you see accurately reflects what you'll face on test day.
1Z0-829 Domain Distribution
Handling Date, Time, Text, Numeric and Boolean Values
Controlling Program Flow
Utilizing Java Object-Oriented Approach
Handling Exceptions

Working with Streams and Lambda Expressions
Java Platform Overview and Packaging
Java I/O API and Securing Applications
Every question is written by certified engineers against the 2026 1Z0-829 exam objectives. These are original practice questions — not dumps — so you build real understanding rather than memorising answers.
Both the mock exam and practice test use the same question bank. The difference is in how you use them — and when to use each during your 1Z0-829 study plan.
Practice test — for learning
Use the 1Z0-829 practice test when you are studying a domain. Answer questions, read every explanation immediately, and build understanding. Do 10–30 questions per domain per session. This is your primary study tool for the first 4 weeks.
Go to practice test →Mock exam — for simulation
Use the 1Z0-829 mock exam in the final 1–2 weeks before your test date. Complete a 60 or 120-question session without stopping, manage your time, then review all results at the end. This builds exam-day stamina and surfaces final weak spots.

A developer is writing a method that reads a file and processes its content. The method must ensure that if an IOException occurs during reading, the method throws a custom ApplicationException that wraps the original IOException, and that any resources opened are closed properly. Which approach correctly implements this requirement?

Answer all 8 questions to see your domain score breakdown
Sitting the 1Z0-829 under real exam conditions is a skill in itself. Candidates who underperform often do so not because of knowledge gaps, but because of poor time management or test anxiety. Use your final mock exam sessions to address both.
The 1Z0-829 exam lasts 90 minutes. Do not spend more than 90 seconds on any single question on the first pass. Flag difficult ones and return to them after completing the rest.
On every question, immediately eliminate obviously wrong choices. Even if you are unsure between two options, narrowing to two doubles your odds. Most 1Z0-829 distractors contain a subtle error — re-read the scenario constraint before committing to the answer that sounds most familiar.
Oracle writes many 1Z0-829 questions as realistic scenarios. Read the final sentence first — it tells you what is being asked. Then re-read the scenario with the question in mind to avoid wasting time on irrelevant details.
The real 1Z0-829 is a mental marathon lasting 90 minutes. In the week before your exam, complete at least two full timed mock sessions on separate days to build concentration stamina. If you cannot stay focused for 90 minutes in practice, you will struggle on exam day.

Scaled scoring
The 1Z0-829 uses scaled scoring — your raw percentage correct is converted to a score out of 1000. Consistently scoring above 80% on mock exams puts you well above the 680/1000 threshold, giving you a buffer for any unexpected question types on the real exam.
Yes. Courseiva provides free 1Z0-829 mock exam questions across all official exam domains. The platform includes timed simulation, per-domain score breakdown, missed-question review, and readiness tracking. No account required — free forever, supported by advertising.
The practice test is optimised for learning: you see explanations after each question immediately. The mock exam is optimised for simulation: you answer all questions under time pressure and review at the end. Use practice tests for studying and mock exams for benchmarking.
Aim for consistent scores of 80% or above on full-length 1Z0-829 mock exams before booking your test date. The official passing score of 680/1000 corresponds to roughly 72–75% correct answers, so an 80% buffer accounts for difficulty variation and question styles on the real exam.
Most candidates who pass 1Z0-829 on their first attempt complete 3–5 full-length mock exams in the two weeks before their test. This is enough to identify final weak spots, build stamina, and verify readiness without over-stressing or running out of fresh questions.
No — all Courseiva questions are original, written by certified engineers against public Oracle exam blueprints. Exam dumps are memorised real exam questions shared illegally. Using dumps violates your Oracle certification agreement and can result in your certification being revoked. Our questions make you genuinely competent, not just test-day lucky.
Track your mock exam scores, see per-domain analytics, and benchmark readiness across every certification.
