In Scala TreeSet class, the find() method is utilized to return an element that satisfies a given predicate in the TreeSet.

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 TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val t1 = TreeSet(2, 4, 6, 7, 8, 9
          
        // Print the TreeSet
        println(t1
          
        // Applying find() method  
        val result = t1.find(x => {x % 7 == 0})
          
        // Displays output 
        println("Element divisible by 7: " + result)
          
    


Output:

TreeSet(2, 4, 6, 7, 8, 9)
Element divisible by 7: Some(7)

Example #2:




// Scala program of find() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val t1 = TreeSet(2, 4, 6, 7, 8, 9
          
        // Print the TreeSet
        println(t1
          
        // Applying find() method  
        val result = t1.find(x => {x % 10 == 0})
          
        // Displays output 
        println("Element divisible by 10: " + result)
          
    


Output:

TreeSet(2, 4, 6, 7, 8, 9)
Element divisible by 10: None
