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 appped 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
