       One of the good feature that Scala Supports is function Currying (this concept is taken from Haskell). This feature is least used during Application Development. Now lets explore what is Currying Actually with an example……… scala> def mul(x:Int, y:Int):Int = x*y mul: (x: Int, y: Int)Int  scala> mul(2,4) res30: Int = 8…

Sets in Scala with examples

Methods of List Object in Scala

Creating lists from their elements: List.apply A literal like List(1, 2, 3) is simply the application of the object List to the elements 1, 2, 3. That is, it is equivalent to List.apply(1, 2, 3): scala>List.apply(1, 2, 3) res53: List[Int] = List(1, 2, 3) Creating a range of numbers: List.range scala>List.range(1,10) res37: List[Int] = List(1,…

Lists in Scala with examples

Scala Lists are always immutable and dynamically growable (but arrays are fixed in Scala once you create with some size ). If you want Mutable List then prefer to use ListBuffer(it is in scala.collection.mutable  package). Here will see about creation of List and operations on it.
