Even if we change the order of execution still they produce the same results.3. In FP, the order of execution of those Functions does not have much importance because they do not have state and all Functions work independently. In FP Languages, we write programs with a set of Independent Functions. That means all Data is Immutable Data and Functions cannot change state.2. Java SE 8 also have some Functional Constructs (Please refer Java 8 posts for more details) What are the Characteristics of FP?įunctional Programming Languages like Scala have the following CharacteristicsįP Programs does not contain state. Examples of FP Languages:- Scala, Haskell, Earlang etc are popular FP Languages. We write programs by defining a set of Functions and Immutable Data. In Functional Programming, Functions are first class candidates. In simple words, Functional Programming (FP) is one of the popular Programming paradigms, which does computation like Mathematical Functions without Changing State and Mutating Data. In this post, we are going to discuss about the following three popular Programming paradigms one by one and also answer above questions: What are the drawbacks of OOP-Inheritance?.When to use Object Oriented Programming?.What are the major advantages of Functional Programming over Imperative Programming or Object Oriented Programming?.What are the differences between Functional Programming, Imperative Programming(IP) and Object Oriented Programming?.What are the differences between Functional Programming and Object Oriented Programming?.What are the differences between Functional Programming and Imperative Programming?.What are the “Pros & Cons” of Functional Programming?.As a Java/Groovy/Scala Developer or any Functional Programming Developer, we should learn the following questions and answers to clear interviews: As Oracle Corporation has introduced some Functional constructs in Java SE 8, now-a-days most of the Interviewers are interested to ask some questions about Functional Programming.
