Scala TreeSet exists() method with example
In Scala TreeSet class
, the exists() method is utilized to check whether a predicate holds for any of the elements of the TreeSet.
Method Definition: def exists(p: (A) => Boolean): Boolean
Return Type: It returns true if the predicate holds true for any of the elements of the TreeSet or else returns false.
Example #1:
// Scala program of exists() // method // Import TreeSet import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating TreeSet val t 1 = TreeSet( 1 , 3 , 2 , 7 , 6 , 5 ) // Print the TreeSet println(t 1 ) // Applying exists() method val result = t 1 .exists(x => {x % 7 == 0 }) // Displays output println( "Element divisible by 7 exists: " + result) } } |
Output:
TreeSet(1, 2, 3, 5, 6, 7) Element divisible by 7 exists: true
Example #2:
// Scala program of exists() // method // Import TreeSet import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating TreeSet val t 1 = TreeSet( 1 , 3 , 2 , 7 , 6 , 5 ) // Print the TreeSet println(t 1 ) // Applying exists() method val result = t 1 .exists(x => {x == 10 }) // Displays output println( "Element 10 exists: " + result) } } |
Output:
TreeSet(1, 2, 3, 5, 6, 7) Element 10 exists: false
