In Scala Stack class
, the mkString() method is utilized to display all the elements of the stack in a string along with a separator.
Method Definition: def mkString(sep: String): String
Return Type: It returns all the elements of the stack in a string along with a separator.
Example #1:
// Scala program of mkString() // method // Import Stack import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating stack
val s 1 = Stack( 1 , 2 , 3 , 4 )
// Print the stack
println(s 1 )
// Applying mkString method
val result = s 1 .mkString( ", " )
// Display output
print( "Stack: " + result)
}
} |
Output:
Stack(1, 2, 3, 4) Stack: 1, 2, 3, 4
Example #2:
// Scala program of mkString() // method // Import Stack import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating stack
val s 1 = Stack( "Geeks" , "for" , "Geeks" )
// Print the stack
println(s 1 )
// Applying mkString method
val result = s 1 .mkString( ", " )
// Display output
print( "Stack: " + result)
}
} |
Output:
Stack(Geeks, for, Geeks) Stack: Geeks, for, Geeks
