Scala Bitsets are sets of non-negative integers which are represented as variable-size arrays of bits packed into 64-bit words. The exists() method tests whether a predicate holds for at least one element of this iterable collection.
Method Definition: def exists()
Return Type: It returns false if this iterable collection is empty, otherwise true.
Example #1:
// Scala program of exists() // method import scala.collection.immutable.BitSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating BitSet
val s 1 = BitSet( 1 , 2 , 3 , 4 , 5 )
// Applying exists method
val result = s 1 .exists(y => {y % 3 == 0 })
// Displays output
println(result)
}
} |
Output:
true
Example #2:
// Scala program of exists() // method import scala.collection.immutable.BitSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating BitSet
val s 1 = BitSet( 1 , 2 , 3 , 4 , 5 )
// Applying exists method
val result = s 1 .exists(y => {y % 7 == 0 })
// Displays output
println(result)
}
} |
Output:
false
