Example #1:
// Scala program of exists() // method // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a list val m 1 = List( 1 , 2 , 3 , 4 , 5 ) // Applying exists method val result = m 1 .exists(y => {y % 3 == 0 }) // Displays output println(result) } } |
Output:
true
Example #2:
// Scala program of exists() // method // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a list val m 1 = List( 1 , 2 , 3 , 4 , 5 ) // Applying exists method val result = m 1 .exists(y => {y % 9 == 0 }) // Displays output println(result) } } |
Output:
false
