The forall() method is utilized to check if the given predicate satisfies all the elements of the SortedSet or not.
Method Definition: def forall(p: (A) => Boolean): Boolean
Return Type: It returns true if the stated predicate holds true for all the elements of the SortedSet else it returns false.
Example #1:
// Scala program of forall() // method import scala.collection.immutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(3, 6, 12, 9, 21)
// Applying forall method
val result = s1.forall(y => {y % 3 == 0})
// Displays output
println(result)
}
} |
Output:
true
Example #2:
// Scala program of forall() // method import scala.collection.immutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args:Array[String])
{
// Creating a SortedSet
val s1 = SortedSet(3, 7, 12, 9, 21)
// Applying forall method
val result = s1.forall(y => {y % 3 == 0})
// Displays output
println(result)
}
} |
Output:
false
