Example #1:
// Scala program of init() // method // Creating object object GfG
{ // Main method
def main(args:Array[String])
{
// Creating a set
val s1 = Set(1, 2, 3, 4, 5)
// Applying init method
val result = s1.init
// Display output
println(result)
}
} |
Output:
Set(5, 1, 2, 3)
Example #2:
// Scala program of init() // method // Creating object object GfG
{ // Main method
def main(args:Array[String])
{
// Creating a set
val s1 = Set(16, 22, 3, 41, 51)
// Applying init method
val result = s1.init
// Display output
println(result)
}
} |
Output:
Set(41, 22, 3, 16)
