// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a queue
val q 1 = Queue( 1 , 2 , 3 , 4 )
// Print the queue
println(q 1 )
// Applying mkString method
val result = q 1 .mkString( ", " )

print( "Queue: " + result)
}
} |
Output:
Queue(1, 2, 3, 4) Queue: 1, 2, 3, 4
Example #2:
// Scala program of mkString() // method // Import Queue import scala.collection.mutable. _

{ // Main method
def main(args : Array[String])
{
// Creating a queue
val q 1 = Queue( "Geeks" , "Will" , "Rule" )
// Print the queue
println(q 1 )
// Applying mkString method
val result = q 1 .mkString( ", " )
// Display output
print( "Queue: " + result)
}
