The emptyIterator() method of Java Collections returns an iterator with no elements. This method is immutable. That is, we can not do any modifications after creating this method.

Syntax:

Iterator<data_type> object = Collections.emptyIterator();

where,

data_type is the type of iterator object
object is the data to create an iterator

Parameters: It will accept no parameters.

Return Type: It will return an empty iterator.

Exceptions: It will not raise any exceptions.

Example 1:

Java

import java.util.*;

public class GFG {

    public static void main(String[] args)
    {
        // create an empty iteratoe
        Iterator<String> i = Collections.emptyIterator();

        // display the iterator
        System.out.println(i);
    }
}

Output

java.util.Collections$EmptyIterator@3d075dc0

Example 2:

Java

// Java program to display the next element
import java.util.*;

public class GFG {

    public static void main(String[] args)
    {
        // create an empty iteratoe
        Iterator<String> i = Collections.emptyIterator();

        // display the iterator next element
        System.out.println(i.hasNext());
    }
}
