In Scala immutable TreeSet class the toList() method is utilised to return a list consisting of all the elements of the TreeSet.
Method Definition: def toList: List[A]
Return Type: It returns a list consisting of all the elements of the TreeSet.
Example #1:
// Scala program of toList() // method // Import TreeSet import scala.collection.immutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 3 , 1 , 5 , 2 , 4 )
// Print the TreeSet
println(t 1 )
// Applying toList method
val result = t 1 .toList
// Display output
print( "Elements in the list: " )
for (elem < - result)
print(elem + " " )
}
} |
Output:
TreeSet(1, 2, 3, 4, 5) Elements in the list: 1 2 3 4 5
Example #2:
// Scala program of toList() // method // Import TreeSet import scala.collection.immutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( "u" , "a" , "i" , "o" , "e" )
// Print the TreeSet
println(t 1 )
// Applying toList method
val result = t 1 .toList
// Display output
print( "Elements in the list: " )
for (elem < - result)
print(elem + " " )
}
} |
Output:
TreeSet(a, e, i, o, u) Elements in the list: a e i o u
