Return Type: It returns true if both the queues are same or else returns false.

Example #1:




// Scala program of equals() 
// method 
  
// Import Queue  
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating queues 
        val q1 = Queue(1, 3, 2, 7, 6, 5
          
        val q2 = Queue(1, 3, 2, 7, 6, 5
          
        // Print the queue
        println("Queue_1: " + q1)
          
        println("Queue_2: " + q2)
          
        // Applying equals method 
        val result = q1.equals(q2
          
        // Displays output 
        print("Queue_1 = Queue_2: " + result)
    
Output:
Queue_1: Queue(1, 3, 2, 7, 6, 5)
Queue_2: Queue(1, 3, 2, 7, 6, 5)
Queue_1 = Queue_2: true

Example #2:




// Scala program of equals() 
// method 
  
// Import Queue  
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String])

        val q1 = Queue(1, 3, 2, 7, 6, 5
          
        val q2 = Queue(5, 3, 2, 7, 6, 1
          
        // Print the queue
        println("Queue_1: " + q1)
          
        println("Queue_2: " + q2)
          
        // Applying equals method 
        val result = q1.equals(q2
          
        // Displays output 
        print("Queue_1 = Queue_2: " + result)
