In this section, you will get the detailed explanation about the
next() method of
interface Iterator. We are going to use next()
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 next() method through the following java program. This method returns next element in the iteration in case the iteration has more than one element. This means that if the iteration has more than one element then the next() method will return the next element. However, if no more element exist then it throws NoSuchElementException.
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 first which will check if there is another element or not and if there exist another element then it will return that (next element) with the help of next() method. Hence we get the following output.
Here is the code of program:
Output of the program:
