Error while iterating through HashMap in Java

Question

I'm trying to iterate through a HashMap like this:

for (Map.Entry<String, Integer> entry : map.entrySet()) {
    String key = entry.getKey();
    Integer value = entry.getValue();
}

but I get this error:

entry cannot be resolved

Is this the wrong way to do it? From what I can tell, this seems to work for others.

Just curious, why are you iterating over entrySet() instead of iterating over keySet()? BTW that code works for me. — dic19

You should use an Iterator. Check out the docs

try this

for(Iterator<Map.Entry<String,Integer>> it = map.entrySet().iterator(); it.hasNext();)
{
    Map.Entry<String,Integer> entry = it.next();
    String key = entry.getKey();
    Integer value = entry.getValue();
}
