Scala Queue find() method with example
• Last Updated : 24 Oct, 2019

The find() method is utilized to return an element that satisfy a given predicate in the queue.

Method Definition: def find(p: (A) => Boolean): Option[A]

Return Type: It returns the first element that satisfies a given predicate if present or else it returns None.

Example #1:

 `// Scala program of find() ``// 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 find method ``        ``val` `result ``=` `q``1``.find(x ``=>` `{x ``%` `7` `==` `0``}) ``         ` `        ``// Displays output ``        ``print(``"Element divisible by 7: "` `+ result)``    ``} ``} `
Output:
```Queue(1, 3, 2, 7, 6, 5)
Element divisible by 7: Some(7)
```

Example #2:

 `// Scala program of find() ``// 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 find method ``        ``val` `result ``=` `q``1``.find(x ``=>` `{x ``%` `10` `==` `0``}) ``         ` `        ``// Displays output ``        ``print(``"Element divisible by 10: "` `+ result)``    ``} ``} `
Output:
```Queue(1, 3, 2, 7, 6, 5)
Element divisible by 10: None
```
