Java SE 17 Developer (Exam 1Z0-829) Programmers Guide

A comprehensive guide to the Java programming language and both the Java SE 21 and Java SE 17 Developer certification exams, this unique tutorial and reference features a rigorous introduction to programming in Java in addition to meticulous coverage of the exam objectives you need to review to pass the 1Z0-830 and 1Z0-829 exams.

Fully updated to reflect changes in the latest exams, it features an increased focus on analyzing code scenarios--not just individual language constructs. Each exam objective is thoroughly addressed, along with the newest features and APIs, and best practices for taking the exam. The only book you need to study for Java SE 21 or Java SE 17 Developer certification, it features

  • Easy-to-find coverage of key topics relevant to each exam objective

  • An introduction to essential concepts in object-oriented programming (OOP) and functional-style programming

  • In-depth coverage of declarations, access control, operators, flow control, OOP techniques, lambda expressions, streams, modules, concurrency, Java I/O, key API classes, and much more

  • Program output demonstrating expected results from complete Java programs

  • Unique diagrams to illustrate important concepts, such as Java I/O, modules, and streams

  • Extensive use of Unified Modeling Language (UML) to illustrate program design

  • Dozens of review questions with annotated answers to help prepare for the exam and a complete mock exam

Part I provides comprehensive coverage of new topics that have come into Java 21 since the release of Java 17 and are included in the objectives for the new exam: pattern matching for objects, sequenced collections, and virtual threads. Part II focuses on the objectives for the Java SE 17 Developer Exam. Appendices in both parts of this guide provide the relevant references to chapters where the exam objectives are covered.
