Imagine writing Java code that reads like the problem statement, code that's highly expressive, concise, easy to read and modify, and has reduced complexity. With the functional programming capabilities in Java, that's not a fantasy. This book will guide you from the familiar imperative style through the practical aspects of functional programming, using plenty of examples. Apply the techniques you learn to turn highly complex imperative code into elegant and easy-to-understand functional-style code. Updated to the latest version of Java, this edition has four new chapters on error handling, refactoring to functional style, transforming data, and idioms of functional programming. Don't struggle with the limitations of the imperative style; instead learn to combine object-oriented programming with the functional style to reduce the accidental complexity. Harness the functional programming capabilities of Java to create applications where the program reveals its intentions and your team can quickly understand and modify code to align with changing business requirements. Unlock the power of lambda expressions and the Streams API to turn the oft-written spaghetti code into highly concise, expressive, elegant, and maintainable code. See how Streams make the arduous task of parallelizing code as easy as flipping a switch when superior speed is necessary. Apply design patterns built around lambda expressions, safely manage resource allocations, use memoization, and learn to transform data into different forms, all while honoring immutability, and providing thread safety to leverage lazy evaluation for efficiency and parallel execution for performance. Move beyond the basics, explore the idioms for writing functional programs. Learn to think functionally by refactoring legacy code into the functional style. And, if your code runs aground due to failures, learn to properly handle errors the functional way. Don't drown in theory; instead learn the practical functional programming techniques to create superior Java code. What You Need: Java version 8 or newer.
Java Functional Programming - Lambda and Stream Practice Tests
Learning is incomplete without challenging questions to assess the knowledge gained. There are courses and books available on Functional Programming & Stream API, which cover these topics in detail, but simply watching the video lectures or finishing the book will not give enough confidence unless the knowledge is validated. Practice tests in this course will not only help you to assess your current knowledge of these topics but will also help you to revise the topics quickly. Questions are designed to challenge your understanding of the topics. Detailed explanations for all the questions are also provided for your reference. Functional programming is not a new concept. Lambdas were implemented in other languages much before they were introduced in Java. Before JDK 8, anonymous inner classes with a single method was the closest Java came to functional programming but with lots of boilerplate code. If anyone wants to really appreciate the implementation of lambda expressions in java, it is necessary to know the anonymous inner classes in depth and to understand anonymous inner class you need to have knowledge of Regular and method-local inner classes. You may face lots of questions in interviews or written tests where you are asked to convert anonymous inner class syntax to lambda expression and vice versa. Therefore I decided to start with questions on inner classes and then go on with Lambda expression, method references, built-in functional interfaces and finally end this test series with questions on Stream API.
