A java set of Shorts can be converted to an Indexed Sequence in Scala by utilizing toIndexedSeq method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work else an error will occur.
Now, lets see some examples and then discuss how it works in details.
Example:1#
// Scala program to convert Java set // to an Indexed Sequence in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating set of Shorts in Java val set = new java.util.HashSet[Short]() // Adding Shorts to the set set.add(100) set.add(1000) set.add(999) // Converting set to an Indexed Sequence val ind = set.toIndexedSeq // Displays Indexed Sequence println(ind) } } |
Output:
Vector(100, 999, 1000)
Example:2#
// Scala program to convert Java set // to an Indexed Sequence in Scala // Importing Scala's JavaConversions object import scala.collection.JavaConversions._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating set of Shorts in Java val set = new java.util.HashSet[Short]() // Adding Shorts to the set set.add(-199) set.add(-1000) set.add(-200) // Converting set to an Indexed Sequence val ind = set.toIndexedSeq // Displays Indexed Sequence println(ind) } } |
Output:
Vector(-199, -1000, -200)
