Scala TreeSet init() method with example

Last Updated : 02 Nov, 2019

In Scala 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

// Scala program of init() 
// method 

// Import TreeSet
import scala.collection.mutable._

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating TreeSet
        val t1 = TreeSet(1, 3, 2, 7, 6, 5) 
        
        // Print the TreeSet
        println(t1)
       
        // Applying init() method  
        val result = t1.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

// Scala program of init() 
// method 

// Import TreeSet
import scala.collection.mutable._

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating TreeSet
        val t1 = TreeSet(1, 3, 12, 7, 16, 5) 
        
        // Print the TreeSet
        println(t1)
       
        // Applying init() method  
        val result = t1.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)
