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 elementimport 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
