Taschenbuch. Etat : Neu. Neuware - Learn object-oriented programming in Java through 100 clear, practical, and progressive mini exercises.This fifth volume in the 100 Java Mini Exercises series is dedicated to one of the most important steps for anyone who wants to truly understand Java: classes, objects, attributes, constructor…s, encapsulation, and small object-oriented systems.If you already know variables, conditionals, loops, arrays, strings, and methods, this book will help you take the next step: stop writing programs with loose data and start organizing your code around real-world entities.Throughout the book, you will learn how to create classes such as: Person, Student, Product, Book, BankAccount, Employee, Customer, Order, Invoice, Reservation, Course, and many more.Each exercise is designed to help you understand one specific concept without unnecessary theory. You will begin by creating simple classes. Then you will add instance methods, constructors, private attributes, getters, setters, validations, the this keyword, objects inside other objects, and arrays of objects.The goal is to help you understand object-oriented programming step by step, with everyday examples and easy-to-follow Java code.In this book, you will learn how to: - create your own classes in Java;- create objects using new;- work with attributes and instance methods;- use constructors to initialize objects;- protect data with private;- use getters and setters;- validate data inside a class;- understand the this keyword;- create objects related to other objects;- work with arrays of objects;- build small object-oriented console systems.This is not a heavy theory book. It is a hands-on practice book.Each exercise includes a statement, a goal, a complete Java solution, a step-by-step explanation, an object-oriented programming note, and a possible improvement.If you want to understand OOP in Java without getting lost in complicated explanations, this book will guide you from your first class to your first small object-oriented systems.100 Java Mini Exercises: Object-Oriented Programming is the ideal volume to strengthen your Java learning and prepare for the next step: working with collections and dynamic lists such as ArrayList and HashMap.

Paperback. Etat : new. Paperback. Learning Java is not just about writing programs that work when everything goes right. It is also about knowing what to do when the user types the wrong thing, when a value does not make sense, when a file is missing, or when an operation can crash the program.100 Mini Java Exercises: Exceptions… and Validation is Book 8 in the 100 Mini Java Exercises series, a practical collection designed to help you learn Java by writing code from the very first page.In this volume, you will work on one of the most important skills for moving beyond beginner code: building programs that are safer, more stable, and better prepared for real-world mistakes.Across 100 progressive exercises, you will practice try-catch, concrete exception types, number validation, safer input with Scanner, empty text checks, protected objects, safer file reading, CSV line validation, and stronger console menus.Each exercise includes a prompt, a clear goal, a complete Java solution, a step-by-step explanation, a note about validation or exceptions, and a possible improvement so you can keep practicing.This book is ideal for students, self-taught learners, future developers, and anyone who already knows the basics of Java and wants to write code that does not break so easily.You do not need frameworks, databases, graphical interfaces, or external libraries. You only need Java, a console, and the willingness to practice with clear, practical examples.In this book, you will learn how to: Use try-catch to handle runtime errors.Recognize exceptions such as ArithmeticException, NumberFormatException, InputMismatchException, IOException, and more.Validate ages, grades, prices, percentages, and menu options.Read user input more safely with Scanner.Check empty strings, spaces, lengths, and basic text formats.Protect objects with constructors, setters, and validation methods.Read TXT and CSV files without blindly trusting their content.Create console menus that stay stable when the user makes a mistake.Build small final applications that combine validation, objects, lists, and files.If you want to move past fragile beginner programs and start writing safer Java code, this book will guide you one exercise at a time.Because a good programmer does not only know how to make a program work.A good programmer also knows how to prepare it for when something goes wrong.

Paperback. Etat : new. Paperback. If you have already taken your first steps with Java and want to level up for real, this book is the next step you need.100 Mini Java Exercises: Conditionals and Loops is the second book in a 12-volume collection built to help you learn Java in a progressive, practical way without unnecessary co…mplications. After learning in the first volume how to use variables, collect input, and perform basic calculations, now it is time for your programs to start making decisions, repeating tasks, and controlling what happens more effectively.Because programming is not just about calculating.Programming is about deciding which path to follow, validating bad input, repeating processes efficiently, and building small applications that respond to the user.In this book, you will work through a clear and carefully planned progression so you can move forward with confidence: simple conditionals with if and elsemultiple conditions with else ifoption selection with switchfor loopswhile loopsdata validationbasic menusmore complete and realistic console programsAcross its 100 mini exercises, this volume will help you build a solid foundation in control logic, one of the most important parts of programming. You will not find random exercises here, but a structured path designed to make learning feel logical and to let the reader notice real progress in both difficulty and skill.On top of that, every exercise follows a teaching format designed to make understanding easier: objectivetaskhintsfull codestep-by-step explanationsample runextra challengeThat makes this book especially useful both for someone studying on their own and for anyone who wants to reinforce classwork, practice from scratch, or get more comfortable with Java in a clear and structured way.This second volume holds a key place in the collection, because it is the book where the reader leaves behind linear programs and starts building programs that react, decide, repeat, and validate.If you are looking for a Java book for beginners that helps you move from the basics to much stronger programming logic, this volume gives you exactly that: real practice, progressive difficulty, and useful learning from page one.Start giving smarter instructions to your programs.Keep moving forward in the collection.And become, exercise by exercise, a more complete programmer.

Paperback. Etat : new. Paperback. Take your Java skills beyond writing code that simply works.In Book 9 of the 100 Java Mini Exercises series, you will learn how to analyze the steps a program follows, compare different solutions, and choose algorithms that are clear, reliable, and efficient.Through 100 practical, progressive ex…ercises, you will explore the essential algorithms every Java learner should understand. You will begin with traversals, accumulators, counters, maximums, minimums, and basic efficiency. From there, you will work with linear search, binary search, classic sorting methods, string algorithms, recursion, divide-and-conquer strategies, merge sort, quick sort, and complete applied challenges.Each exercise includes: a clear problem statement;a specific learning objective;complete and functional Java code;a step-by-step explanation;an algorithm note;an improvement challenge for further practice.Inside this book, you will learn how to: count iterations, comparisons, swaps, and recursive calls;search arrays using linear and binary search;find first, last, and repeated appearances;sort numbers, strings, and objects;implement bubble sort, selection sort, and insertion sort;analyze palindromes, anagrams, frequencies, and repeated characters;understand base cases and recursive calls;build recursive binary search;implement merge sort and quick sort;compare O(n), O(log n), O(n2), and O(n log n) solutions;combine multiple algorithms in realistic console applications.The book uses clear American English, gradual explanations, and fully developed examples. It is designed for self-taught programmers, students, teachers, and anyone who wants to strengthen their algorithmic thinking without getting lost in excessive mathematical theory.You do not need to memorize every solution.The goal is to recognize the patterns behind each problem, understand why an algorithm works, and develop the ability to rebuild and adapt it when needed.If you have already worked with Java fundamentals, arrays, methods, objects, collections, files, and exceptions, this book will help you take the next major step: from writing code to understanding how that code solves problems.Continue the journey and prepare for Book 10, where these algorithms will become practical tools inside complete Java console projects.
