Scala Iterator toList() method with example

Scala Iterator toSet() method with example

Last Updated : 26 Jul, 2019

The toSet() method belongs to the concrete value member of the class Abstract Iterator. It is defined in the class IterableOnceOps.

Method Definition: def toSet[B >: A]: immutable.Set[B]

Return Type: It returns a set from the stated collection.

Example #1:

// Scala program of toSet() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating a Iterator  
        val iter = Iterator(5, 6, 8, 9) 
          
        // Applying toSet method  
        val result = iter.toSet 
          
        // Displays output 
        println(result) 
      
    } 
} 

Output:

Set(5, 6, 8, 9)

Example #2:

// Scala program of toSet() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an empty Iterator  
        val iter = Iterator() 
          
        // Applying toSet method  
        val result = iter.toSet 
          
        // Displays output 
        println(result) 
      
    } 
} 

Output:

Set()
