Scala Queue contains() method with example

Last Updated : 18 Oct, 2019

The contains() method is utilized to test if an element is present in the queue or not.

Method Definition: def contains[A1 >: A](elem: A1): Boolean Return Type: It returns true if the element is present in the queue, else it returns false.

Example #1:

Scala

// Scala program of contains() 
// method 

// Import Queue  
import scala.collection.mutable._

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a queue 
        val q1 = Queue(10, 11, 12, 13, 14)
        
        // Print the queue
        println(q1)
        
        // Applying contains() method 
        val result = q1.contains(12)
        
        // Display output
        print("Queue contains 12: " + result)   
        
    } 
}

Output:

Queue(10, 11, 12, 13, 14)
Queue contains 12: true

Example #2:

Scala

// Scala program of contains() 
// method 

// Import Queue  
import scala.collection.mutable._

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a queue 
        val q1 = Queue(10, 11, 12, 13, 14)
        
        // Print the queue
        println(q1)
        
        // Applying contains() method 
        val result = q1.contains(20)
        
        // Display output
        print("Queue contains 20: " + result)   
        
    } 
}

Output:

Queue(10, 11, 12, 13, 14)
Queue contains 20: false
