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
