# 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` `q``1` `=` `Queue(``1``, ``3``, ``2``, ``7``, ``6``, ``5``) ``         ` `        ``val` `q``2` `=` `Queue(``1``, ``3``, ``2``, ``7``, ``6``, ``5``) ``         ` `        ``// Print the queue``        ``println(``"Queue_1: "` `+ q``1``)``         ` `        ``println(``"Queue_2: "` `+ q``2``)``         ` `        ``// Applying equals method ``        ``val` `result ``=` `q``1``.equals(q``2``) ``         ` `        ``// 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` `q``1` `=` `Queue(``1``, ``3``, ``2``, ``7``, ``6``, ``5``) ``         ` `        ``val` `q``2` `=` `Queue(``5``, ``3``, ``2``, ``7``, ``6``, ``1``) ``         ` `        ``// Print the queue``        ``println(``"Queue_1: "` `+ q``1``)``         ` `        ``println(``"Queue_2: "` `+ q``2``)``         ` `        ``// Applying equals method ``        ``val` `result ``=` `q``1``.equals(q``2``) ``         ` `        ``// 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
```
