Оглавление

The following table provides a breakdown of this book's exam coverage for the Java SE 17 Developer (1Z0-829) exam, showing you the chapter where each objective or subobjective is covered.

Exam Objective Chapter
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 expressions 1, 2, 4
Manipulate text, including text blocks, using String and StringBuilder classes 4
Manipulate date, time, duration, period, instant and time-zone objects using Date-Time API 4
Controlling Program Flow
Create program flow control constructs including if/else, switch statements and expressions, loops, and break and continue statements 3
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 1, 7
Create classes and records, and define and use instance and static fields and methods, constructors, and instance and static initializers 5, 6, 7
Implement overloading, including var-arg methods 5
Understand variable scopes, use local variable type inference, apply encapsulation, and make objects immutable 1, 6, 7, 8
Implement polymorphism and differentiate object type versus reference type. Perform type casting, identify object types using instanceof operator and pattern matching 3, 6, 7
Create and use interfaces, identify functional interfaces, and utilize private, static, and default interface methods 7, 8
Create and use enumerations with fields, methods and constructors 7
Handling Exceptions
Handle exceptions using try/catch/finally, try-with-resources, and multi-catch blocks, including custom exceptions 11
Working with Arrays and Collections
Create Java arrays, List, Set, Map, and Deque collections, and add, remove, update, retrieve and sort their elements 4, 9
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 10
Perform decomposition, concatenation and reduction, and grouping and partitioning on sequential and parallel streams 10, 13
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 12
Compile Java code, produce modular and non-modular jars, runtime images, and implement migration using unnamed and automatic modules 12
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 13
Develop thread-safe code, using different locking mechanisms and concurrent API 13
Process Java collections concurrently including the use of parallel streams 13
Using Java I/O API
Read and write console and file data using I/O Streams 14
Serialize and de-serialize Java objects 14
Create, traverse, read, and write Path objects and their properties using java.nio.file API 14
Accessing databases using JDBC
Create connections, create and execute basic, prepared and callable statements, process query results and control transactions using JDBC API 15
Implementing Localization
Implement localization using locales, resource bundles, parse and format messages, dates, times, and numbers including currency and percentage values 11
