val result = q 1 .find(x => {x % 7 == 0 })
print( "Element divisible by 7: " + result)
}
}

Output:
Queue(1, 3, 2, 7, 6, 5)
Element divisible by 7: Some(7)
Example #2:
import scala.collection.mutable. _
object GfG
{
def main(args : Array[String])
{
val q 1 = Queue( 1 , 3 , 2 , 7 , 6 , 5 )
println(q 1 )
val result = q 1 .find(x => {x % 10 == 0 })
print( "Element divisible by 10: " + result)
}
}
