Convert Iterator to Iterable in Java

Let’s say the following is our Iterator with Integer values −

Iterator<Integer>iterator = Arrays.asList(20, 40, 60, 80, 100, 120, 150, 200).iterator();

Now, convert the Iterator to Iterable −

Iterable<Integer>iterable = StreamSupport.stream(Spliterators.spliteratorUnknownSize(iterator, 0),false).collect(Collectors.toList());

Example

Following is the program to convert Iterator to Iterable in Java −

import java.util.*; import java.util.stream.Collectors; import java.util.stream.StreamSupport; public class Demo {    public static void main(String[] args) {       Iterator<Integer>iterator = Arrays.asList(20, 40, 60, 80, 100, 120, 150, 200).iterator();       Iterable<Integer>iterable = StreamSupport.stream(Spliterators.spliteratorUnknownSize(iterator, 0), false).collect(Collectors.toList());       System.out.println("Iterable = ");       iterable.forEach(System.out::println);    } }

Output

Iterable = 20 40 60 80 100 120 150 200
