Java Certification (1Z0-829) Topic-wise Tests Part-2 [2025]

Be well versed with the latest features of Java 17 and test your preparation for the Java SE 17 Developer (1Z0-829) exam.

Oracle has released the latest certification on the Long Term Support built of Java 17. It has many new features such as Switch Expressions, Pattern matching, Text Blocks, Records and Sealed Classes, etc. and the ease of coding has increased from earlier versions. It is good to have this armor in your arsenal to do more effective coding.

As of 27th Jan 2025, this course has helped 8 students to pass the OCP: Java SE 17 Developer (1Z0-829) exam.

This course covers questions on the following 7 exam topics:

1. Working with Arrays and Collections (Covers Set, Map, and Deque collections and sorting)

2. Working with Streams and Lambda expressions

3. Managing concurrent code execution

4. Using Java I/O API

5. Accessing databases using JDBC

6. Implementing Localization

7. Packaging and deploying Java code and use the Java Platform Module System

This course covers above 7 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 1Z0-829 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.

NOTE:

These tests are divided into 2 parts (courses):

1. Java Certification (1Z0-829) Topic-wise Tests Part-1 [2025]: Contains 602 questions

This course covers below 5 exam topics:

• Handling date, time, text, numeric and boolean values

• Controlling Program Flow

• Utilizing Java Object-Oriented Approach

• Exception Handling

• Working with Arrays and Collections (Covers Arrays and List API)

2. Java Certification (1Z0-829) Topic-wise Tests Part-1 [2025]: Contains 610 questions [THIS COURSE]

This course covers below 7 exam topics:

• Working with Arrays and Collections (Covers Set, Map, and Deque collections, and sorting)

• Working with Streams and Lambda expressions

• Managing concurrent code execution

• Using Java I/O API

• Accessing databases using JDBC

• Implementing Localization

• Packaging and deploying Java code and use the Java Platform Module System

So, you will have total 1212 questions to solve.

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 1Z0-829 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.

Course Structure:

Test 1 covers following topics:

Working with Arrays and Collections

• Create Java arrays, List, Set, Map, and Deque collections, and add, remove, update, retrieve and sort their elements ["Java arrays" and "List API" are covered in Test-6 of Topic Wise Part-1 course, this test covers remaining topics (Set, Map, and Deque collections and sorting)]

Working with Streams and Lambda expressions

• Use Java object and primitive Streams, including lambda expressions implementing functional interfaces, to supply, filter, map, consume, and sort data [This test covers lambda expressions, method references and built-in functional interfaces (Supplier, Function & Predicate)]

Test 2 covers following topics:

Working with Streams and Lambda expressions

• Use Java object and primitive Streams, including lambda expressions implementing functional interfaces, to supply, filter, map, consume, and sort data [Primitive Streams are covered in next test]

Test 3 covers following topics:

Working with Streams and Lambda expressions

• Use Java object and primitive Streams, including lambda expressions implementing functional interfaces, to supply, filter, map, consume, and sort data [Only Primitive Streams are covered in this test, rest of the topics were covered in previous tests]

• Perform decomposition, concatenation and reduction, and grouping and partitioning on sequential and parallel streams

Managing concurrent code execution

• Create worker threads using Runnable and Callable, manage the thread lifecycle, including automations provided by different Executor services and concurrent API

• Develop thread-safe code, using different locking mechanisms and concurrent API

• Process Java collections concurrently including the use of parallel streams

Test 4 covers following topics:

Using Java I/O API

• Read and write console and file data using I/O Streams

• Serialize and de-serialize Java objects

• Create, traverse, read, and write Path objects and their properties using java.nio.file API

Candidates are also expected to:

• Use Annotations such as Override, Functionalnterface, Deprecated, SuppressWarnings, and SafeVarargs.

Test 5 covers following topics:

Accessing databases using JDBC

• Create connections, create and execute basic, prepared and callable statements, process query results and control transactions using JDBC API

Implementing Localization

• Implement localization using locales, resource bundles, parse and format messages, dates, times, and numbers including currency and percentage values

Test 6 covers following topics:

Packaging and deploying Java code and use the Java Platform Module System

• Define modules and their dependencies, expose module content including for reflection. Define services, producers, and consumers

• Compile Java code, produce modular and non-modular jars, runtime images, and implement migration using unnamed and automatic modules

Last but not the least, RELAX, and enjoy the tests!
