Scala Iterator zip() method with example

  • Last Updated : 13 Aug, 2019

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

Method Definition: val result = iter.zip(iter1)

Return Type: It returns a new Scala iterator holding pairs of corresponding elements in the iterator and the size of the number of elements returned is minimum of the sizes of both the iterators.

Example #1:




// Scala program of zip()
// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating the first Iterator 
        val iter = Iterator(1, 2, 3, 4, 5, 6)
          
        // Creating the second iterator
        val iter1 = Iterator(7, 8, 9, 10)
          
        // Applying zip method 
        val result = iter.zip(iter1)
          
        // Displays output
        println(result)
      
    }
}
Output:
non-empty iterator

Example #2:




// Scala program of zip()
// method
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating the first Iterator 
        val iter = Iterator()
          
        // Creating the second iterator
        val iter1 = Iterator(0, 0, 0, 0)
          
        // Applying zip method 
        val result = iter.zip(iter1)
          
        // Displays output
        println(result)
      
    }
}
Output:
empty iterator
