Sharpen your Java skills and boost your potential as an IT specialist. This book introduces you to the basic Java features and APIs needed to prepare for a career in programming and development.

You’ll first receive an introduction to Java and then explore language features ranging from comments though exception/error handling, focusing mainly on language syntax and a few select syntax-related APIs. This constitutes the heart of the book, and you’ll use these building blocks to construct simple Java programs, and learn where Java’s implementations of expressions (and operators), and statements diverge from other languages. The final few chapters tour some additional APIs such as the Math class, related types, String and StringBuffer, and System.

Along the way you’ll discover some interesting programs, such as Graph (a sine/cosine wave-plotting application) and WC (a word-counting application). Two
appendixes provide quick references to Java’s supported reserved words, and to Java’s supported operators. Equipped with this knowledge, Learn Java Fundamentals will provide you the pathway to explore additional APIs on your own, and increase your Java awareness.

Java is like a two-sided coin. From one side, it’s a computer programming language. Conversely, it’s a virtual platform (the hardware and software context in which a program runs) for running programs written in that language. Java is a programming language with many features that are identical to those found in the C and C++ languages. This is no accident. One of Java’s initial goals was to make it easy for C/C++ programmers to migrate to Java to quickly build up an initial pool of programmers that would help Java become successful. Java is a virtual platform that executes Java programs. Unlike real platforms that consist of a microprocessor (such as an Intel or AMD processor) and operating system (such as Windows 11), the Java platform consists of virtual machine and execution environment software. The Java Development Kit (JDK) provides the necessary software for creating Java applications, which are a category of Java programs with a single entry point of execution. They contrast with Java applets, another category of Java programs that run embedded in web pages. Applets are rarely used these days.

What You’ll Learn:
Understand the basics of Java applications and APIs
Study language features such as comments, identifiers, variables, types, and literals.
Explore operators, expressions, statements, and other key features such as classes, objects, class extension, and class abstraction.
