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:
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 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());
}
}
Output
false
