Overview

Are you ready to pass OCP- Java SE 8 Programmer II certification and prove your competency to recruiters and employers alike?As of 27th Jan 2025, the practice test questions have helped 124 students to pass the OCP Certification (1Z0-809) exam. Are you ready to join them and take a leap in your Java programming career?OCP - Java SE 8 Programmer II - Exam Information: [NEW FORMAT effective September 1, 2022]Exam Code: 1Z0-809Duration: 120 minutes Questions #: 68 (Multiple Choice / Multiple Select)Passing score: 65% This course covers all the EXAM topics in orderly fashion, which helps students to assess their preparation for respective topic. This course can be used as a learning aid while preparing for OCP certification to test your preparation for each topic while preparing for that topic. Topic-wise questions helps in identifying week areas thus more focus can be given to those specific topics. Course highlights: 1. All questions are multiple choice or multiple select questions.2. You have around 2.4 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 OCP 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:- Java Class Design Implement encapsulationImplement inheritance including visibility modifiers and compositionImplement polymorphismOverride hashCode, equals, and toString methods from Object classCreate and use singleton classes and immutable classesDevelop code that uses static keyword on initialize blocks, variables, methods, and classes - Advanced Java Class DesignDevelop code that uses abstract classes and methodsDevelop code that uses the final keywordCreate inner classes including static inner class, local class, nested class, and anonymous inner classUse enumerated types including methods, and constructors in an enum typeDevelop code that declares, implements and/or extends interfaces and use the Override annotation.Create and use Lambda expressionsTest 2 Covers following topics:- Generics and CollectionsCreate and use a generic classCreate and use ArrayList, TreeSet, TreeMap, and ArrayDeque objectsUse java.util.Comparator and java.lang.Comparable interfacesCollections Streams and FiltersIterate using forEach methods of Streams and ListDescribe Stream interface and Stream pipelineFilter a collection by using lambda expressionsUse method references with StreamsTest 3 Covers following topics:- Lambda Built-in Functional InterfacesUse the built-in interfaces included in the java.util.function package such as Predicate, Consumer, Function, and SupplierDevelop code that uses primitive versions of functional interfacesDevelop code that uses binary versions of functional interfacesDevelop code that uses the UnaryOperator interface - Java Stream APIDevelop code to extract data from an object using peek() and map() methods including primitive versions of the map() methodSearch for data by using search methods of the Stream classes including findFirst, findAny, anyMatch, allMatch, noneMatchDevelop code that uses the Optional classDevelop code that uses Stream data methods and calculation methodsSort a collection using Stream APISave results to a collection using the collect method and group/partition data using the Collectors classUse flatMap() methods in the Stream APITest 4 Covers following topics:- Exceptions and AssertionsUse try-catch and throw statementsUse catch, multi-catch, and finally clausesUse Autoclose resources with a try-with-resources statementCreate custom exceptions and Auto-closeable resourcesTest invariants by using assertions - Use Java SE 8 Date/Time APICreate and manage date-based and time-based events including a combination of date and time into a single object using LocalDate, LocalTime, LocalDateTime, Instant, Period, and DurationWork with dates and times across timezones and manage changes resulting from daylight savings including Format date and times valuesDefine and create and manage date-based and time-based events using Instant, Period, Duration, and TemporalUnitTest 5 Covers following topics:- Java I/O FundamentalsRead and write data from the consoleUse BufferedReader, BufferedWriter, File, FileReader, FileWriter, FileInputStream, FileOutputStream, ObjectOutputStream, ObjectInputStream, and PrintWriter in the IO package. - Java File I/O (NIO.2)Use Path interface to operate on file and directory pathsUse Files class to check, read, delete, copy, move, manage metadata of a file or directoryUse Stream API with NIO.2 - LocalizationRead and set the locale by using the Locale objectCreate and read a Properties fileBuild a resource bundle for each locale and load a resource bundle in an applicationTest 6 Covers following topics:- Java ConcurrencyCreate worker threads using Runnable, Callable and use an ExecutorService to concurrently execute tasksIdentify potential threading problems among deadlock, starvation, livelock, and race conditionsUse synchronized keyword and java.util.concurrent.atomic package to control the order of thread executionUse java.util.concurrent collections and classes including CyclicBarrier and CopyOnWriteArrayListUse parallel Fork/Join FrameworkUse parallel Streams including reduction, decomposition, merging processes, pipelines and performance. - Building Database Applications with JDBCDescribe the interfaces that make up the core of the JDBC API including the Driver, Connection, Statement, and ResultSet interfaces and their relationship to provider implementationsIdentify the components required to connect to a database using the DriverManager class including the JDBC URLSubmit queries and read results from the database including creating statements, returning result sets, iterating through the results, and properly closing result sets, statements, and connectionsMore information on detailed curriculum and assumptions to be followed for examination are available on oracle certification page. NOTE: If you prefer exam simulation to assess your preparation for the certification exam, then you can enroll in my other course titled "Java Certification: OCP (1Z0-809) Exam Simulation [2025]", which contains the same questions but pattern in Exam Simulation course is similar to 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.Last but not the least, RELAX, and enjoy the tests!!Copyright 2025 Udayan KhattryAll rights reserved.
