Java Iterator Hacker Rank Solution

Problem

Java Iterator class can help you to iterate through every element in a collection. Here is a simple example:

import java.util.*;public class Example{    public static void main(String []args){        ArrayList mylist = new ArrayList();        mylist.add("Hello");        mylist.add("Java");        mylist.add("4");        Iterator it = mylist.iterator();        while(it.hasNext()){            Object element = it.next();            System.out.println((String)element);        }    }}

In this problem you need to complete a method func. The method takes an ArrayList as input. In that ArrayList there is one or more integer numbers, then there is a special string “###”, after that there are one or more other strings. A sample ArrayList may look like this:

element[0]=>42 element[1]=>10 element[2]=>"###" element[3]=>"Hello" element[4]=>"Java"

You have to modify the func method by editing at most 2 lines so that the code only prints the elements after the special string “###”. For the sample above the output will be:

Hello Java

Note: The stdin doesn’t contain the string “###”, it is added in the main method.
