Scala immutable TreeSet find() method
In Scala immutable TreeSet class, the find() method is utilised 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.immutable._ // 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.immutable._ // 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) } } |

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