Scala Vector

Vector is a general-purpose, immutable data structure. It provides random access of elements. It is good for large collection of elements.

It extends an abstract class AbstractSeq and IndexedSeq trait.

Scala Vector Example

import scala.collection.immutable._
object MainObject{
    def main(args:Array[String]){
        var vector:Vector[Int] = Vector(5,8,3,6,9,4) //Or
        var vector2 = Vector(5,2,6,3)
        var vector3 = Vector.empty
        println(vector)
        println(vector2)
        println(vector3)
    }
}

Output:

Vector(5, 8, 3, 6, 9, 4)
Vector(5, 2, 6, 3)
Vector(

Scala Vector Example

In the following example, we have created a vector. You can also add new element and merge two vectors.

import scala.collection.immutable._
object MainObject{
    def main(args:Array[String]){
        var vector = Vector("Hocky","Cricket","Golf")
        var vector2 = Vector("Swimming")
        print("Vector Elements: ")
        vector.foreach((element:String) => print(element+" "))
        var newVector  = vector :+ "Racing" 							// Adding a new element into vector
        print("\nVector Elements after adding: ")
        newVector.foreach((element:String) => print(element+" "))
        var mergeTwoVector = newVector ++ vector2   					// Merging two vector
        print("\nVector Elements after merging: ")
        mergeTwoVector.foreach((element:String) => print(element+" "))
        var reverse = mergeTwoVector.reverse       	 					// Reversing vector elements
        print("\nVector Elements after reversing: ")
        reverse.foreach((element:String) => print(element+" "))
        var sortedVector = mergeTwoVector.sorted    					// Sorting vector elements
        print("\nVector Elements after sorting: ")
        sortedVector.foreach((element:String) => print(element+" "))
    }
}

Output:

Vector Elements: Hocky Cricket Golf 
Vector Elements after adding: Hocky Cricket Golf Racing 
Vector Elements after merging: Hocky Cricket Golf Racing Swimming 
Vector Elements after reversing: Swimming Racing Golf Cricket Hocky 
Vector Elements after sorting: Cricket Golf Hocky Racing Swimming
