This course covers above 8 EXAM topics in orderly fashion, which will help students to assess their preparation for respective topic. This course can be used as a learning aid while preparing for 1Z0-819 certification to test your preparation for each topic while preparing for that topic. 

Topic-wise questions helps in identifying weak areas thus more focus can be given to those specific topics.



These tests are divided into 2 parts (courses):

1. Java Certification (1Z0-819) Topic-wise Tests – Part 1: Contains 535 questions

This course covers below 5 exam topics: 

  • Working with Java data types
  • Controlling Program Flow
  • Java Object-Oriented Approach
  • Exception Handling
  • Working with Arrays and Collections

2. Java Certification (1Z0-819) Topic-wise Tests – Part 2: Contains 567 questions [THIS COURSE]

This course covers below 8 exam topics:

  • Working with Streams and Lambda expressions
  • Java Platform Module System
  • Concurrency
  • Java I/O API
  • Secure Coding in Java SE Application
  • Database Applications with JDBC
  • Localization
  • Annotations

So, you will have total 1102 questions to solve.


If you prefer exam simulation, then you can enroll in below courses:

1. Java Certification (1Z0-819) Exam Simulation – Part 1: Contains 300 questions

2. Java Certification (1Z0-819) Exam Simulation – Part 2: Contains 300 questions

3. Java Certification (1Z0-819) Exam Simulation – Part 3: Contains 251 questions

4. Java Certification (1Z0-819) Exam Simulation – Part 4: Contains 251 questions

These 4 courses contain the same 1102 questions as in 2 topic-wise courses. Each practice test of these exam simulation courses contain questions on all the exam topics, similar to what is expected in real exam.

Disclaimer: These questions are not real examination questions / dumps. These questions  are designed based on real exams in terms of pattern and complexity to help you understand the type of expected questions from each exam objective.

Course highlights:

1. All questions are multiple choice or multiple select questions.

2. You have around 2 minutes to complete each question which is more than the exam timing. 

3. This practice tests will explain in detail why the right answer is the right answer, in review phase. Understanding the explanation will help in instillation of concepts. Relevant hints and how to approach a question in real examination setting is also provided in explanation.

4. At the end of the practice exam, check your progress and review each question and sort by 1Z0-819 knowledge area, correct answers, wrong answers, skipped questions and questions marked for review.

5. You can take these exams multiple times till concepts are deeply ingrained.
