1z1-819 Exam FAQ
The package includes 297 practice questions for the 1z1-819 exam, all with verified answers. The same content is available in three formats, so you can switch freely.
The 1z1-819 exam contains 80 questions to complete within 90 minutes minutes. Rehearsing under the same limit on the simulator builds calm, automatic pacing.
The PDF reads on phones, tablets, and computers, and it prints cleanly for candidates who like marking notes on paper. The PC file is an interactive simulator that makes rehearsal engaging. The online file is the updated edition of the PC version: intelligent functions, real-test simulation, and no limit on installation devices. All three carry the same questions and answers.
Oracle recommends but does not require candidates to first obtain the Oracle Certified Professional: Java SE 11 Programmer I (1Z0-815) certification. However, 1Z0-819 can be taken directly without 1Z0-815.
- I/O (Fundamentals and NIO2) (7%)
- Working with Java data types (12%)
- Working with Streams and Lambda expressions (13%)
Plan your hours according to each topic's weight.
1z1-819 requires 68% to pass, and the official exam fee is $245 USD. Fixing both numbers early keeps your practice target and your budget on the same page.
