Given an Iterator, the task is to convert it into Spliterators in Java.

Examples:

  Input: Iterator = {1, 2, 3, 4, 5}  Output: {1, 2, 3, 4, 5}    Input: Iterator = {'G', 'e', 'e', 'k', 's'}  Output: {'G', 'e', 'e', 'k', 's'}

Approach:

Get the Iterator.
Convert the iterator to Spliterator using Spliterators.spliteratorUnknownSize() method.
Return the Spliterator.

Below is the implementation of the above approach:

   // Java program to get a Spliterator 
// from a given Iterator 
  
import java.util.*; 
  
class GFG { 
  
    // Function to get the Spliterator 
    public static <T> Spliterator<T> 
    getSpliteratorFromIterator(Iterator<T> iterator) 
    { 
        return Spliterators 
            .spliteratorUnknownSize(iterator, 0); 
    } 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // Get the Iterator 
        Iterator<Integer> 
            iterator = Arrays.asList(1, 2, 3, 4, 5) 
                           .iterator(); 
  
        // Get the Spliterator from the Iterator 
        Spliterator<Integer> 
            si = getSpliteratorFromIterator(iterator); 
  
        // Print the elements of Spliterator 
        si.forEachRemaining(System.out::println); 
    } 
} 
 
  

Output:

  1  2  3  4  5
