Scala Queue equals() method with example

The equals() method is utilized to check if two queues consists of the same elements in the same order.

Method Definition: def equals(o: Any): Boolean

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])
    {

        // Creating queues
        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)
    }
}

Output:

Queue_1: Queue(1, 3, 2, 7, 6, 5)
Queue_2: Queue(5, 3, 2, 7, 6, 1)
Queue_1 = Queue_2: false
