Scala immutable TreeSet forall() method
In Scala immutable TreeSet class
, the forall() method is utilized to check if a predicate holds true for all the elements of the TreeSet.
Method Definition: def forall(p: (A) => Boolean): Boolean
Return Type: It returns true if the predicate holds true for all the elements of the TreeSet or else returns false.
Example #1:
import scala.collection.immutable. _
object GfG
{
def main(args : Array[String])
{
val t 1 = TreeSet( 2 , 4 , 6 , 7 , 8 , 9 )
println(t 1 )
val result = t 1 .forall(x => {x % 7 == 0 })
println( "All the elements are divisible by 7: " + result)
}
}
|
Output:
TreeSet(2, 4, 6, 7, 8, 9)
All the elements are divisible by 7: false
Example #2:
import scala.collection.immutable. _
object GfG
{
def main(args : Array[String])
{
val t 1 = TreeSet( 2 , 4 , 6 , 8 )
println(t 1 )
val result = t 1 .forall(x => {x % 2 == 0 })
println( "All the elements are even: " + result)
}
}
|
Output:
TreeSet(2, 4, 6, 8)
All the elements are even: true
