It is is the process of building software by composing pure functions, avoiding shared state, mutable data, and side-effects. Functional programming is declarative rather than imperative, and application state flows through pure functions. We call it as a declarative type of Continue Reading

Introduction to Java 8

Reading Time: < 1 minute The Functional Features of Java8 Java 8 was a major release in terms of language and APIs. The language includes several ideas from functional programming like behavior parameterization, passing lambda expression as methods, processing data with stream pipelines etc. The following presentation describes the functional programming add on in Java 8. We will be introducing the lambda expression, Functional Interfaces, Default methods and Stream API in Java Continue Reading
