Question

I apologize for the basic question but my newness to Java is causing me some frustration and I am unable to find an elegant way to do this from my searches.

I want to iterate through a linked list using a For construct but also have an numerical iterator so that I can break the loop after a certain number of iterations.

I have this LL that I am iterating through:

LinkedList<SearchResult> docSearch;

I tried doing it like this but then only the iterator part worked (the result was always stuck on the first entry for each iteration)

for (SearchResult result : docSearch) while (iter2 < 50)  { 

//do stuff
iter2 = iter2 + 1;
}

Any advice is appreciated

If you have to do that sort of checking, then I would just do it with an if in the block.

for (SearchResult result : docSearch)  {
  if (iter2 >= 50) break;

  //do stuff
  iter2 += 1;
}
