Scala Iterator toString() method with example

Scala Iterator toSet() method with example

The toString() method belongs to the concrete value member of the class Abstract Iterator. It is utilized to convert the stated iterator to a string.

Method Definition: def toString(): String

Return Type: It returns a string from the stated iterator.

Example #1:

// Scala program of toString() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating a Iterator  
        val iter = Iterator(2, 1, 10) 
          
        // Applying toString method  
        val result = iter.toString 
          
        // Displays output 
        println(result) 
      
    } 
} 

Output:

non-empty iterator

Example #2:

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

Output:

empty iterator

In above example, iterator is empty so produced result is also empty iterator.
