How to convert Java Set of floats to Vector in Scala?

By IncludeHelp Last updated : November 14, 2024

Java Sets

Sets in java is a data structure to store unique elements.

Example

set (5.1, 9.04, 23.5)

Scala Vectors

Vectors in Scala are immutable-indexed data structures that provide random access to the elements of the vectors.

Example

vector(5.1, 9.04, 23.5)

Convert Java Set of floats to Vector

Converting of data structure from one (Java set) to another is possible and is done using the toVector method in Scala.

Syntax

set.toVector

Program to illustrate the conversion of java set of floats to vector

import scala.jdk.CollectionConverters._

object myObject {
  def main(args: Array[String]): Unit = {
    val javaSet = new java.util.HashSet[Float]()
    
    javaSet.add(5.1f)
    javaSet.add(9.04f)
    javaSet.add(23.5f)
    
    println("Java Set : " + javaSet)
    
    val scalaVector = javaSet.asScala.toVector
    println("Scala Vector : " + scalaVector)
  }
}

Output

Java Set : set(5.1, 9.04, 23.5)
Scala Vector: vector(5.1, 9.04, 23.5)
