Scala Collections - Find Method

find() method is method used by Iterators to find an element which satisfies a given predicate.

Syntax

The following is the syntax of find method.

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

Here, p: (A) => Boolean is a predicate or condition to be applied on each element of the iterator. This method returns the Option element containing the matched element of iterator which satisfiles the given condition.

Usage

Below is an example program of showing how to use find method −

Example

object Demo {
   def main(args: Array[String]) = {
      val iterator = Iterator(3, 6, 9, 4, 2)
      //apply operation
      val result = iterator.find(x=>{x % 3 == 0})
      //print result
      println(result)      
   }
}

Save the above program in Demo.scala. The following commands are used to compile and execute this program.

Command

\>scalac Demo.scala
\>scala Demo
