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

It seems you've provided a detailed overview of a Java programming course that covers various topics relevant to the Oracle Certified Professional, Java SE 8 Programmer exam (1Z0-829). This course is designed to help candidates prepare for the exam by providing practice questions with explanations. Here's a summary of what each test in the course covers:

1. Test 1 focuses on working with arrays and collections, including creating Java arrays, Lists, Sets, Maps, and Deques, as well as sorting their elements. It also introduces the use of Streams and lambda expressions to perform operations like filtering, mapping, and consuming data.

2. Test 2 continues with the use of Streams and lambda expressions, but this time it focuses on object streams (as opposed to primitive streams covered in the next test). It also covers decomposition, concatenation, reduction, grouping, and partitioning on sequential and parallel streams. Additionally, it touches upon managing concurrent code execution with threads and Executor services.

3. Test 3 is dedicated to working with primitive Streams, which are a different subset of data types in Java Stream API. It continues with the topics covered in Test 2 regarding concurrency and thread management, including locking mechanisms and concurrent API usage.

4. Test 4 covers using the Java I/O API, including reading and writing console and file data, serializing and de-serializing objects, and working with the java.nio.file API.

5. Test 5 involves accessing databases using JDBC (Java Database Connectivity) API, and implementing Localization in Java by using locales and resource bundles to handle language-specific data.

6. Test 6 covers packaging and deploying Java code, as well as using the Java Platform Module System. It includes defining modules with dependencies, exposing module content, and setting up services, producers, and consumers. It also touches upon migrating existing Java applications to a modular format.

The course also reminds candidates to familiarize themselves with annotations like @Override, @FunctionalInterface, @Deprecated, @SuppressWarnings, and @SafeVarargs.

Each test is designed to be taken multiple times to help reinforce the concepts and ensure a deep understanding of the material covered by the exam objectives. Remember to take breaks, stay relaxed, and use the explanations provided after each question to enhance your learning experience. Good luck with your studies!
