Te addString method utilized to append the elements of the Scala Iterator to a String Builder.This method is same as addString() method but here a start, a separator and an end is also included.

Method Definition: def addString(b: mutable.StringBuilder, start: String, sep: String, end: String): mutable.StringBuilder

Where, sep is the separator stated.

Return Type: It returns the elements of the Iterator in the String Builder and a start, a separator and an end is also included here.

Example #1:






// Scala program of addString() method
// with a start, a separator and an
// end
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a Iterator
        val m1 = Iterator(1, 3, 4, 8)
          
        // Applying addString method 
        val result = m1.addString(new StringBuilder(), "=>", "|", ".")
          
        // Displays output
        println(result)
    }
}
Output:
=>1|3|4|8.

Example #2:




// Scala program of addString() method
// with a start, a separator and an
// end
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a Iterator
        val m1 = Iterator(1, 3, 3, 8)
          
        // Applying addString method 
        val result = m1.addString(new StringBuilder(), "=>", "|", ".")
          
        // Displays output
        println(result)
    }
}
Output:
=>1|3|3|8.

So, here the identical element is not removed like in maps.
