Master modern Java programming - from your first "Hello, World!" to professional-quality applications - using Java 25 and IntelliJ Community Edition.
Modern Java Programming for Beginners featuring Java 25 and IntelliJ Community Edition is your complete, step-by-step guide to learning the world's most trusted programming language, updated for the newest Long-Term-Support (LTS) release. Whether you're an absolute beginner or transitioning from another language, this book will help you confidently write, test, and deploy real-world Java applications using modern tools and practices.
You'll start by setting up Java 25 and IntelliJ IDEA Community Edition, then learn the language fundamentals: syntax, variables, control flow, methods, and arrays. From there, you'll dive into object-oriented programming, functional programming with lambdas, collections, and the Stream API.
Each concept is explained clearly, reinforced with examples, and tied to hands-on coding exercises. You'll also explore modern Java 25 features, including:
- Compact source files and instance main methods (JEP 512)
- Module import declarations (JEP 511)
- Scoped values (JEP 506)
- Performance and memory improvements with the new JVM
- Flexible constructors, updated pattern matching, and structured concurrency
Finally, you'll learn to use professional development tools: building projects with Maven and Gradle, debugging and testing with JUnit 5, and managing code in Git - all within IntelliJ IDEA.
By the end of this book, you will:- Understand the foundations of the Java language and JVM
- Write clean, efficient, and maintainable Java code
- Build, package, and run complete Java applications
- Be ready to move into GUI, web, or enterprise development
If you're ready to start coding with confidence and learn Java the modern way - this book will show you how.
