Using iterator() Method

To sequentially access elements of an array list, we use the iterator() method. We must import java.util.Iterator package to use this method. For example,


\begin{lstlisting} import java.util.ArrayList; import java.util.Iterator; \par c... ...m.out.print(iterate.next()); System.out.print('', ''); } } } \end{lstlisting}

Output looks like ArrayList: Dog, Cat, Horse, Zebra,. hasNext() returns true if there is a next element in the array list. next() returns the next element in the array list.
