This tutorial discusses how to use the hasNext() method of the Iterator class to find if there is any more element.
In this section, you will get the detailed explanation about the
method of interface Iterator. We are going to use
method of interface Iterator
in Java. The description of the code is given below for the usage of the method.
Description of the code:
Here, you will get to know about the hasNext() method through the following java program. True is return by this method in case the iteration has more elements. This means that if the iteration has more elements then the hasNext() method will return true rather than throwing an exception.
In the program code given below, we have taken a string of elements. We have converted this string of elements into a list of array and then we have applied the hasNext() method which returns true because there are more elements in the list. Hence we get the following output.
Here is the code of program:
Output of the program:
In this section you have learned how to use the hasNext() method of Iterator class.
