# Scala Queue filter() method with example

The filter() method is utilized to return a new queue that consists of all the elements that satisfy a given predicate.

Method Definition: def filter(pred: (A) => Boolean): Queue[A]

Return Type: It returns a new queue that consists of all the elements that satisfy a given predicate.

Example #1:

 `// Scala program of filter() ``// 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``) ``         ` `        ``// Print the queue``        ``println(q``1``)``         ` `        ``// Applying filter method ``        ``val` `result ``=` `q``1``.filter(x ``=>` `{x ``%` `2` `==` `1``}) ``         ` `        ``// Displays output ``        ``print(``"Odd elements: "` `+ result)``    ``} ``} `

Output:

```Queue(1, 3, 2, 7, 6, 5)
Odd elements: Queue(1, 3, 7, 5)
```

Example #2:

 `// Scala program of filter() ``// 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``) ``         ` `        ``// Print the queue``        ``println(q``1``)``         ` `        ``// Applying filter method ``        ``val` `result ``=` `q``1``.filter(x ``=>` `{x ``%` `3` `==` `0``}) ``         ` `        ``// Displays output ``        ``print(``"Elements divisible by 3: "` `+ result)``    ``} ``} `

Output:

```Queue(1, 3, 2, 7, 6, 5)
Elements divisible by 3: Queue(3, 6)
```
