{"product_id":"b0h8qccjj9","title":"Java 25 Programming in 21 Days: A Hands-On Course in Modern Java (Learn Programming in 21 Days)","description":"\u003cp\u003eJava runs the world's software, and Java 25 is the most approachable it has ever been. This book teaches you to use it well — the whole language, on one real project. Most people meet Java as a big, ceremonious language and never see how cleanly its modern form fits together.  Java 25 Programming in 21 Days  takes a different path: a twenty-one-day, hands-on course that teaches the whole language on one real project — a command-line library tool you build from scratch in  Java . Each day is a single sitting that builds on the last, so the language assembles in your hands instead of landing all at once.\u003c\/p\u003e\n\n\u003cp\u003eYou start with the language core — the JDK 25 toolchain and  JShell , types and text, decisions and loops, arrays, and methods, using Java 25's new compact source files so your first program has no boilerplate. You move on to objects and the type system: classes, inheritance, interfaces,  records ,  sealed types  and  pattern matching , and generics. Then you make it modern and finished — collections, exceptions, lambdas and the  Streams API , file and data IO, and concurrency with  virtual threads  — ending with a modular, tested, packaged application you can ship.\u003c\/p\u003e\n\n\u003cp\u003eEvery day is self-contained: clear objectives, plain-English explanations, real Java listings, clean diagrams, and a closing Summary, Q\u0026amp;A, and Workshop so the skill sticks. The code targets  Java 25 (LTS) , the current release.\u003c\/p\u003e\n\n\u003cp\u003eYour 21-day path Week 1 — The Java Language Core\u003c\/p\u003e\n\n\u003cp\u003eDay 1: Getting Started with Modern Java 25\u003cbr\u003e\nDay 2: Variables, Types, and Operators\u003cbr\u003e\nDay 3: Strings, Text, and Text Blocks\u003cbr\u003e\nDay 4: Decisions and Branching\u003cbr\u003e\nDay 5: Loops and Iteration\u003cbr\u003e\nDay 6: Arrays and the Arrays Class\u003cbr\u003e\nDay 7: Methods\u003c\/p\u003e\n\n\u003cp\u003eWeek 2 — Object-Oriented Java and the Type System\u003c\/p\u003e\n\n\u003cp\u003eDay 8: Classes and Objects\u003cbr\u003e\nDay 9: Constructors, Encapsulation, and Immutability\u003cbr\u003e\nDay 10: Inheritance and Polymorphism\u003cbr\u003e\nDay 11: Interfaces and Default Methods\u003cbr\u003e\nDay 12: Records and Enums\u003cbr\u003e\nDay 13: Sealed Types and Pattern Matching\u003cbr\u003e\nDay 14: Generics\u003c\/p\u003e\n\n\u003cp\u003eWeek 3 — Modern, Robust, and Concurrent Java\u003c\/p\u003e\n\n\u003cp\u003eDay 15: Collections and Sequenced Collections\u003cbr\u003e\nDay 16: Exceptions and Robust Code\u003cbr\u003e\nDay 17: Lambdas and Functional Interfaces\u003cbr\u003e\nDay 18: The Streams API and Optional\u003cbr\u003e\nDay 19: Files, IO, and Data Formats\u003cbr\u003e\nDay 20: Concurrency with Virtual Threads\u003cbr\u003e\nDay 21: Testing, Packaging, and the Capstone\u003c\/p\u003e\n\n\u003cp\u003eWho it's for Anyone who can already program in some language — students and developers coming from Python, JavaScript, C#, or C++ — who wants to learn Java properly and current.
