Convert an Iterable to Stream in Java
  • Last Updated : 11 Dec, 2018

Given an Iterable, the task is to convert it into Stream in Java.


Input: Iterable = [1, 2, 3, 4, 5]
Output: {1, 2, 3, 4, 5}

Input: Iterable = ['G', 'e', 'e', 'k', 's']
Output: {'G', 'e', 'e', 'k', 's'}


  1. Get the Iterable.
  2. Convert the Iterable to Spliterator using Iterable.spliterator() method.
  3. Convert the formed Spliterator into Sequential Stream using method.
  4. Return the stream.

Below is the implementation of the above approach:

// Java program to get a Stream
// from a given Iterable
import java.util.*;
class GFG {
    // Function to get the Stream
    public static <T> Stream<T>
    getStreamFromIterable(Iterable<T> iterable)
        // Convert the Iterable to Spliterator
            spliterator = iterable.spliterator();
        // Get a Sequential Stream from spliterator
        return, false);
    // Driver code
    public static void main(String[] args)
        // Get the Iterator
            iterable = Arrays.asList(1, 2, 3, 4, 5);
        // Get the Stream from the Iterable
            stream = getStreamFromIterable(iterable);
        // Print the elements of stream
        stream.forEach(s -> System.out.println(s));
