java.util.NoSuchElementException:

The NoSuchElementException in Java is thrown when one tries to access an iterable beyond its maximum limit. This means that, this exception is thrown by various accessor methods to indicate that the element being requested does not exist. The next() method in Java returns the next element in the iteration or NoSuchElementException if the iteration has no more elements. The solution to this exception is to check whether the next position of an iterable is filled or empty . The following methods are used to check the next position:

• hasNext()
• hasMoreElements()
