Reading Time: 5 minutes In this blog, we would be looking at how map() and flatMap() operations work with Option and Future of scala, literally speaking both Futures and Options are very effective features of scala, A Future lets us have a value from some task on a differnt thread and Option provides us a hand from null of java as using null in scala is seen a very bad approach in Continue Reading

Reading Time: 3 minutes In Scala, lots of the things are kind of a magic for Java developers. Sometimes this magic amazes the code but sometimes it has ruined the developer’s life. Today we are going to discuss one of the magic called “For Expression“, “For Comprehension” or as per Java developers like me called “For Loop“. Scala developers familiar with for comprehension and most of them have the idea, Continue Reading

Scala Map

Reading Time: 6 minutes Scala Map is a collection of Key-value pair. A map cannot have duplicate keys but different keys can have same values i.e keys are unique whereas values can be duplicate. Maps in Scala are not language syntax. They are library abstractions that you can extend and adapt. Scala provides mutable and immutable alternatives for maps. Class hierarchy for scala maps is shown below: Image Continue Reading
