In Scala TreeSet class
, the apply() method is utilized to check if some element is present in the TreeSet or not.
Method Definition: def apply(elem: A): Boolean
Return Type: It returns true if the given element is present in the TreeSet or else returns false.
Example #1:
// Scala program of apply() // method // Import TreeSet import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 2 , 1 , 3 , 4 , 5 )
// Print the TreeSet
println(t 1 )
// Applying apply() method
val result = t 1 .apply( 3 )
// Displays output
println( "TreeSet contains '3': " + result)
}
} |
Output:
TreeSet(1, 2, 3, 4, 5) TreeSet contains '3': true
Example #2:
// Scala program of apply() // method // Import TreeSet import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 2 , 1 , 3 , 4 , 5 )
// Print the TreeSet
println(t 1 )
// Applying apply() method
val result = t 1 .apply( 0 )
// Displays output
println( "TreeSet contains '0': " + result)
}
} |
Output:
TreeSet(1, 2, 3, 4, 5) TreeSet contains '0': false
