35. Java Iterator - Java | OOPs | Hackerrank
Java Iterator class can help you to iterate through every element in a collection.
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.
