In Scala immutable TreeSet class
, the init() method is utilized to return a new TreeSet that consists of all the elements except the last one.
Method Definition: def init: TreeSet[A]
Return Type: It returns a new TreeSet that consists of all the elements except the last one.
Example #1:
// Scala program of init() // method // Import TreeSet import scala.collection.immutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 1 , 3 , 2 , 7 , 6 , 5 )
// Print the TreeSet
println(t 1 )
// Applying init() method
val result = t 1 .init
// Displays output
println( "Elements of the TreeSet except the last one: " + result)
}
} |
Output:
TreeSet(1, 2, 3, 5, 6, 7) Elements of the TreeSet except the last one: TreeSet(1, 2, 3, 5, 6)
Example #2:
// Scala program of init() // method // Import TreeSet import scala.collection.immutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 1 , 3 , 12 , 7 , 16 , 5 )
// Print the TreeSet
println(t 1 )
// Applying init() method
val result = t 1 .init
// Displays output
println( "Elements of the TreeSet except the last one: " + result)
}
} |
Output:
TreeSet(1, 3, 5, 7, 12, 16) Elements of the TreeSet except the last one: TreeSet(1, 3, 5, 7, 12)
