how can I get the next object on my linkedlist?

I have a LinkedList of objects in Java and I want to iterate through it, and when I find a specific object there - I want to take the next object (the one that is right next to the first one).

I thought this would solve the case:

listIterator = items.listIterator();
while (listIterator.hasNext() && listIterator.previous().getCode().equals(search.getCurrentCode())) {

    item = listIterator.next();
    result.setCurrentCode(item.getCode());
    break;
}

but I'm getting error:

java.util.NoSuchElementException: null

I think it's because of using .previous, but I don't know how to handle that correctly, how could I solve it then? I'm using previous, but what I want is to use the current element - I thought that's handled by .previous, but apparently it's not.

Your current code fails because You are calling previous, before even start iterating on items. Iteration is done with listIterator.next(); call. You can try the code below.

while (listIterator.hasNext()){
   // iterate always
   item = listIterator.next();
   // if found and an element still exist
   if(item.getCode().equals(search.getCurrentCode() && listIterator.hasNext()){
      // get the next element
      item = listIterator.next();
      result.setCurrentCode(item.getCode());
      break;
   }
}
