public static void main(String[] args) {

List outList = new LinkedList<>();

outList.add("number1");

outList.add("number2");

outList.add("number3");

outList.add("number4");

// Getting Iterator

Iterator outListIterator = outList.iterator();

// Traversing elements

while(outListIterator.hasNext()){

import java.util.List;

public class HashNext {

public static void main(String[] args) {

List outList = new LinkedList<>();
outList.add("number1");
outList.add("number2");
outList.add("number3");
outList.add("number4");
outList.add("number5");
outList.add("number6");
outList.add("number7");
outList.add("number8");

// Getting Iterator

Iterator outListIterator = outList.iterator();

// Traversing elements

while(outListIterator.hasNext()){

//skip 2 times if there are elements
for(int i = 1; i <= 2 && outListIterator.hasNext(); i++)
outListIterator.next();
//print the 3rd element if there is one
if(outListIterator.hasNext())
System.out.println(outListIterator.next());

}

}

}

output
