In Scala Stack class
, the contains() method is utilized to check if an element is present in the stack of not.
Method Definition: def contains(elem: A): Boolean
Return Type: It returns true if the element is present in the stack or else it returns false.
Example #1:
// Scala program of contains() // method import scala.collection.mutable.Stack // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a stack val s 1 = Stack( 1 , 2 , 3 , 4 , 5 ) // Print the stack println(s 1 ) // Applying contains method val result = s 1 .contains( 10 ) // Display output println( "Stack contains element 10: " + result) } } |
Output:
Stack(1, 2, 3, 4, 5) Stack contains element 10: false
Example #2:
// Scala program of contains() // method import scala.collection.mutable.Stack // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a stack val s 1 = Stack( "C++" , "Java" , "Python" , "Scala" ) // Print the stack println(s 1 ) // Applying contains method val result = s 1 .contains( "Scala" ) // Display output println( "Stack contains element Scala: " + result) } } |
Output:
Stack(C++, Java, Python, Scala) Stack contains element Scala: true
