Oracle 1Z0-829 Syllabus Topics:
| Handling date, time, text, numeric and boolean values | - Use primitives and wrapper classes including Math API, parentheses, type promotion, and casting to evaluate arithmetic and boolean expression - Manipulate text, including text blocks, using String and StringBuilder classes - Manipulate date, time, duration, period, instant and time-zone objects using Date-Time API |
| Controlling Program Flow | - Create program flow control constructs including if/else, switch statements and expressions, loops, and break and continue statements |
| Utilizing Java Object-Oriented Approach | - Declare and instantiate Java objects including nested class objects, and explain the object life-cycle including creation, reassigning references, and garbage collection - Create classes and records, and define and use instance and static fields and methods, constructors, and instance and static initializers - Implement overloading, including var-arg methods - Understand variable scopes, use local variable type inference, apply encapsulation, and make objects immutable - Implement polymorphism and differentiate object type versus reference type. Perform type casting, identify object types using instanceof operator and pattern matching - Create and use interfaces, identify functional interfaces, and utilize private, static, and default interface methods - Create and use enumerations with fields, methods and constructors |
| Handling Exceptions | - Handle exceptions using try/catch/finally, try-with-resources, and multi-catch blocks, including custom exceptions |
| Working with Arrays and Collections | - Create Java arrays, List, Set, Map, and Deque collections, and add, remove, update, retrieve and sort their elements |
| 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 - Perform decomposition, concatenation and reduction, and grouping and partitioning on sequential and parallel streams |
| 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 |
| 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 |
| 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 |
| 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 |
