Are you looking to enhance your Java skills with functional programming? Do you want to write cleaner, more efficient, and more maintainable code? If so, this course is for you! Functional Programming in Java is designed to help Java developers transition from imperative to functional programming paradigms using lambda expressions, functional interfaces, and the Java Stream API.By the end of this course, you'll not only understand the theoretical foundations of functional programming but also gain hands-on experience with real-world coding examples. Whether you're a beginner looking to explore functional programming or an experienced developer seeking to refine your skills, this course provides everything you need to master Java's modern functional programming capabilities.What is Functional Programming?Functional programming is a declarative way of writing code that focuses on what to do rather than how to do it.It avoids changing state and mutable data.Functions are treated as first-class citizens.It makes code more concise, predictable, and easier to test. Java has embraced functional programming since Java 8, introducing features like lambdas, functional interfaces, streams, and method references.What You Will LearnThis comprehensive course covers everything from the fundamentals of functional programming to advanced topics, ensuring you develop a strong understanding of lambda expressions, functional interfaces, and Java Streams. You will explore:Introduction to Functional ProgrammingUnderstanding the paradigm shift from imperative programming to functional programmingHow functional programming improves code readability, reusability, and scalabilityPure Functions in Functional ProgrammingFunctions as First-Class Objects in Functional ProgrammingHigher-order Functions in Functional ProgrammingRules of Pure Functional ProgrammingLambda Expressions in JavaThe power of anonymous functionsWriting clean and concise code using lambda expressionsPractical examples and use cases of lambda functionsFunctional Interfaces in JavaUnderstanding built-in functional interfaces: Function, Predicate, Supplier, and ConsumerExploring BiFunction, BiPredicate, and BiConsumer for handling multiple argumentsWorking with UnaryOperator and BinaryOperatorPrimitive Functional InterfacesSpecialized interfaces for handling primitive types like int, long, and doubleHow these interfaces optimize performance in functional programmingJava Stream APIIntroduction to Streams and Pipelines for Efficient Data ProcessingUsing filter(), map(), flatMap(), and sorted() for data transformationApplying collect(), foreach(), distinct(), limit(), and skip()Aggregation techniques using count(), min(), max()Handling conditions with anyMatch(), allMatch(), and noneMatch()Java Stream Programs for BeginnersOptional Class to handle null pointer exceptionsMethod ReferencesWhy Learn Functional Programming in Java?Functional programming is becoming ly important in modern software development.
