Below is a breakdown of the topics:1. Handling Date, Time, Text, Numeric, and Boolean ValuesUse primitives and wrapper classes, evaluate arithmetic and boolean expressions, and apply precedence rules, type conversions, and casting.Manipulate text using String, StringBuilder, and text blocks.Work with date, time, duration, period, and time-zone objects, including daylight saving time, using the Date-Time API.2. Controlling Program FlowCreate and manage control flow constructs such as if/else, switch statements and expressions, loops, and break/continue statements.3. Using Object-Oriented Concepts in JavaDeclare and instantiate objects, including nested classes, and explain object lifecycles.Create classes, records, and define/instantiate instance and static fields, methods, constructors, and initializers.Implement method overloading, including var-arg methods.Understand variable scopes, apply encapsulation, and create immutable objects.Use local variable type inference.Implement inheritance, including abstract and sealed types, record classes, and overriding methods, including those of the Object class.Use polymorphism, casting, and the instanceof operator with pattern matching and switch constructs.Create and use interfaces with functional methods, and private, static, and default methods.Work with enums including fields, methods, and constructors.4. Handling ExceptionsHandle exceptions with try/catch/finally, try-with-resources, and multi-catch blocks.Create and use custom exceptions.5. Working with Arrays and CollectionsCreate and manipulate arrays, List, Set, Map, and Deque collections, including adding, removing, updating, retrieving, and sorting elements.6. Working with Streams and Lambda ExpressionsUse Java Streams, including lambda expressions implementing functional interfaces, to filter, transform, process, and sort data.Perform decomposition, concatenation, reduction, grouping, and partitioning on sequential and parallel streams.7. Packaging and Deploying Java CodeDefine and expose module content, including by reflection, and declare module dependencies.Compile Java code, create modular/non-modular JARs, runtime images, and implement migration to modules using unnamed/automatic modules.8. Managing Concurrent Code ExecutionCreate platform and virtual threads using Runnable and Callable objects.Manage thread lifecycles and use different ExecutorService implementations and concurrent APIs.Develop thread-safe code with locking mechanisms and process Java collections concurrently with parallel streams.9. Using Java I/O APIRead/write console and file data using I/O Streams.Serialize and deserialize Java objects.Work with Path objects and their properties using the java.nio.file API.10. Implementing LocalizationImplement localization using locales and resource bundles.Parse and format messages, dates, times, and numbers, including currency and percentage values.11. Additional Java FeaturesUnderstand the basics of the Java Logging API.Use annotations like @Override, @FunctionalInterface, @Deprecated, @SuppressWarnings, and @SafeVarargs.Comprehensive Scope of CertificationBy completing this course, you will develop proficiency in:Handling Date, Time, Text, Numeric, and Boolean ValuesControlling Program FlowObject-Oriented Concepts in JavaHandling ExceptionsArrays and CollectionsStreams and Lambda ExpressionsPackaging and Deploying Java CodeManaging Concurrent Code ExecutionJava I/O APILocalizationAdditional Java FeaturesThis comprehensive preparation ensures you are fully equipped to pass the Oracle 1Z0-830 certification and advance your career in Java development.
