Scala ListSet exists() method with example
In Scala ListSet, exists() method is utilized to check if the given predicate satisfies the elements of the listSet or not.
Method Definition: def exists(p: (A) => Boolean): Boolean
Return Type: It returns true if the stated predicate holds true for some elements of the listset else it returns false.
Example 1:
// Scala program of exists() // method import scala.collection.immutable._// Creating object object GfG { // Main method def main(args:Array[String]) { // Creating Listset val m1 = ListSet(1, 2, 3, 4, 5, 7) // Applying exists method val result = m1.exists(_==9) // Displays output println(result) } } |
Output:
false
Example 2:
// Scala program of exists() // method import scala.collection.immutable._// Creating object object GfG { // Main method def main(args:Array[String]) { // Creating listset val m1 = ListSet(1, 2, 3, 4, 5, 7) // Applying exists method val result = m1.exists(_>9) // Displays output println(result) } } |
Output:
false
