Learn the fundamentals of the Java 17 LTS or Java Standard Edition
version 17 Long Term Support release, including basic programming
concepts and the object-oriented fundamentals necessary at all levels of
Java development. Authors Kishori Sharan and Adam L. Davis walk you
through writing your first Java program step-by-step. Armed with that
practical experience, you'll be ready to learn the core of the Java
language. Beginning Java 17 Fundamentals provides over 90 diagrams and
240 complete programs to help you learn the topics faster.
While this book teaches you the basics, it also has been revised to
include the latest from Java 17 including the following: value types
(records), immutable objects with an efficient memory layout; local
variable type inference (var); pattern matching, a mechanism for testing
and deconstructing values; sealed types, a mechanism for declaring all
possible subclasses of a class; multiline text values; and switch
expressions.
The book continues with a series of foundation topics, including using
data types, working with operators, and writing statements in Java.
These basics lead onto the heart of the Java language: object-oriented
programming. By learning topics such as classes, objects, interfaces,
and inheritance you'll have a good understanding of Java's
object-oriented model. The final collection of topics takes what you've
learned and turns you into a real Java programmer.
You'll see how to take the power of object-oriented programming and
write programs that can handle errors and exceptions, process strings
and dates, format data, and work with arrays to manipulate data.
