Java Certification (1Z0-819) Topic-wise Tests Part-1 [2025]

Looks like you've outlined a comprehensive study plan for preparing for the Java Certification (1Z0-819) exam, broken down into four parts with a focus on object-oriented concepts, exception handling, and working with arrays and collections. The courses are designed to simulate the actual exam environment with detailed explanations to ensure a deep understanding of the concepts.

Here's a summary of your course structure:

1. Exam Simulation Part-1 - Focuses on Java data types, control flow statements, and basic object-oriented programming (OOP) concepts like creating and using objects, understanding object lifecycles, and initializing them with instance and static initializer blocks and constructors.

2. Exam Simulation Part-2 - Delves deeper into OOP with fields, methods, and encapsulation, as well as covers subclasses, superclasses (including abstract classes), polymorphism, and object casting. It also includes the introduction of local variable type inference which will be covered for lambda parameters.

3. Exam Simulation Part-3 - Continues with OOP topics such as interfaces, enumerations, and further explores exception handling, including the use of try-with-resources. This part also covers creating custom exceptions.

4. Exam Simulation Part-4 - Concludes with advanced topics on exception handling, arrays, and collections. It includes using List, Set, Map, and Deque collections, convenience methods for collections, and sorting strategies using the Comparator and Comparable interfaces.

Each part of the course provides practice questions to help reinforce learning and prepare you for the real exam. The tests are designed to be timed, with detailed explanations upon completion to ensure you understand not just the why but also the how behind each answer.

The course highlights emphasize the importance of understanding the concepts well enough to apply them in various scenarios and to be prepared for the types of questions you might encounter on the actual certification exam.

Remember, consistent practice and a clear understanding of the topics are key to success in the Java Certification (1Z0-819) exam. Good luck with your studies!
