Java 9 Functional Programming Tutorial

Date: 2017-07-06

This tutorial introduces functional programming in Java 9, contrasting it with object-oriented programming. Functional programming emphasizes immutability and avoids changing state, leading to more readable and testable code. The article demonstrates this using examples involving string concatenation, time retrieval, and list manipulation, highlighting the use of lambda expressions and streams. Streams provide an immutable way to process collections, enabling efficient parallel operations. The role of Optional in handling potentially missing values is also explained, advocating its use where the absence of a result needs explicit representation. Functional programming in Java blends with OOP, improving code quality and testability.
