Scala Map find() method with example
  • Last Updated : 13 Aug, 2019

The find() method is utilized to find the first element of the map that satisfies the given predicate.

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

Return Type: It returns the first element of the map which satisfies the given predicate.

Example #1:




// Scala program of find()
// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating map
        val m1 = Map(3 -> "geeks", 1 -> "for", 2 -> "cs")
          
        // Applying find method
        val result = m1.find(_._2 == "for")
          
        // Displays output
        println(result)
      
    }
}
Output:
Some((1, for))

So, here the second pair which is the first pair that satisfies the given predicate so, the second pair is returned.
Example #2:




// Scala program of find()
// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating map
        val m1 = Map(3 -> "geeks", 1 -> "for", 2 -> "cs", 6 -> "geeks")
          
        // Applying find method
        val result = m1.find(_._2 == "geeks")
          
        // Displays output
        println(result)
      
    }
}
Output:
Some((3, geeks))
