Scala Stack contains() method with example

Last Updated : 03 Nov, 2019

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 s1 = Stack(1, 2, 3, 4, 5)  
          
        // Print the stack 
        println(s1) 
      
        // Applying contains method     
        val result = s1.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 s1 = Stack("C++", "Java", "Python", "Scala")  
          
        // Print the stack 
        println(s1) 
      
        // Applying contains method     
        val result = s1.contains("Scala") 
          
        // Display output 
        println("Stack contains element Scala: " + result)  
  
    }  
}  

Output:

Stack(C++, Java, Python, Scala)
Stack contains element Scala: true
