A java Set of characters can be converted to a Sequence in Scala by utilizing toSeq method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work.
Now, lets see some examples and then discuss how it works in details.
Example:1#
// Scala program to convert Java set // to 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 character in Java
val set = new java.util.HashSet[Char]()
// Adding characters to the set
set.add('a')
set.add('b')
set.add('c')
// Converting set to Sequence
val seq = set.toSeq
// Displays Sequence
println(seq)
}
} |
Output:
ArrayBuffer(a, b, c)
Example:2#
// Scala program to convert Java set // to 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 character in Java
val set = new java.util.HashSet[Char]()
// Adding characters to the set
set.add('d')
set.add('b')
set.add('c')
// Converting set to Sequence
val seq = set.toSeq
// Displays Sequence
println(seq)
}
} |
Output:
ArrayBuffer(b, c, d)
