In Scala Stack class
, the push() method is utilized to add an element on the top of the stack.
Method Definition: def push(elem: A): Stack.this.type
Return Type: It adds an element on the top of the stack.
Example #1:
// Scala program of push() // method import scala.collection.mutable.Stack
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a stack
var s = Stack[Int]()
// Applying push method
s.push( 1 )
s.push( 2 )
s.push( 3 )
s.push( 4 )
// Print the Stack
println(s)
}
} |
Output:
Stack(4, 3, 2, 1)
Example #2:
// Scala program of push() // method import scala.collection.mutable.Stack
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a stack
var s = Stack[String]()
// Applying push method
s.push( "C++" )
s.push( "Java" )
s.push( "Python" )
s.push( "Scala" )
// Print the Stack
println(s)
}
} |
Output:
Stack(Scala, Python, Java, C++)
