A java Set of characters can be converted to a String in Scala by utilizing toString 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 a String 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 characters 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 a String
val str = set.toString
// Displays output
println(str)
}
} |
Output:
[a, b, c]
Here, the duplicate elements are eliminated and the resultant order of the elements in set is same as stated above.
Example:2#
// Scala program to convert Java set // to a String 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 characters 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 a String
val str = set.toString
// Displays output
println(str)
}
} |
Output:
[b, c, d]
Here, the stated set is not in correct order but the resultant output is in proper order.
