Expect 50 questions with a time limit of 90 minutes. The smart move is to treat time as a resource: allocate a rough budget per question, mark the stubborn ones and move on, then return with fresh eyes. Two or three full timed runs in the PracticeTorrent desktop engine — which recreates the real exam environment — will calibrate your pace far better than untimed reading ever could.
No mandatory prerequisites; recommended 6+ months hands-on Java SE experience; prior Java SE 8/11 certification is optional for upgrade Keep in mind that vendors adjust their requirements over time, so verify the current rules on the official exam page (1Z0-829 official exam details) before you schedule anything.

Now the safety net: sit the corresponding 1Z0-829 exam within 60 days of purchase and, if you don't pass, claim a full refund under our 100% Money Back Guarantee by submitting a scanned enrollment slip and the official Score Report PDF within 2 days of the exam; processing finishes within 7 days. Conditions apply: exams taken within 3 days of purchase are excluded, the candidate's name must match the payer's, and free or expired products aren't eligible.

Per the official blueprint, the Oracle Java SE 17 Developer is organized into 10 domains — among them Using Java I/O and NIO.2 API (8%), Packaging and Deploying Java Code with JPMS (8%), Working with Streams and Lambda Expressions (12%). The weights show where the exam spends its questions, so let them guide your study hours. The full domain-and-subtopic breakdown is in the outline section above.

The vendor recommends these official training options:
Training covers the theory well, but self-assessment is what catches weak spots. Once the coursework is done, run the 1Z0-829 practice questions from PracticeTorrent and let your scores reveal what still needs work.
The official fee for the 1Z0-829 exam is USD $245, and passing requires 68%. Remember that the fee buys exactly one attempt — a retake costs the same amount again. That is a good reason to rehearse with the 50 practice questions from PracticeTorrent until you're consistently scoring past the threshold before paying for the real thing.
The Oracle Java SE 17 Developer is the vendor's official exam for the Oracle Certified Professional: Java SE 17 Developer certification, a credential at the Professional level. It is widely recognized because it verifies genuine, job-ready skill — exactly what employers shortlist for. It also connects to related credentials including Oracle Certified Professional: Java SE 11 Developer, Oracle Certified Professional: Java SE 8 Developer, which makes it a solid anchor for a longer certification roadmap.
