how iterate Hash-Map into another method

Question

i have this hash map :

  HashMap<String, String> meMap = new HashMap<String, String>();
                        meMap.put(p.getName(), selState);

how can i iterate it into another method?How can i pass map to another method to iterate it?

Why don't you take a look at [this](http://stackoverflow.com/questions/46898/how-to-efficiently-iterate-over-each-entry-in-a-map?answertab=active#tab-top) for how to iterate the Map. To use the map in another method simple pass the Map to the method. Like So `myIteratingMethod(meMAp)` and the function header like so `private void myIteratingMethod(HashMap<> map)`. — Abbas, Jul 27 '16 at 10:23
@markella Then perhaps try to be more clear in your question. — Abbas, Jul 27 '16 at 10:28
@markella your question is indeed unclear. Explain what you mean by "your link not help me". What happened? IDE showed a message? NullPointerException? Your problem is different? If it's different, please explain why and how. — Sufian, Jul 27 '16 at 11:08

meMap.entrySet() gives you that ability

You can use it like for (Entry<String, String> entry : meMap.entrySet()) {...} or pass to another method

yes i know, but if i pass to an other method this "HashMap" this is underline in red by IDE – markella Jul 27 '16 at 10:25
define function parameter Iterable<> – Dmytro Rostopira Jul 27 '16 at 10:27
public void yourFunction(Iterable<> map) {} – Dmytro Rostopira Jul 27 '16 at 10:29
if you want to pass HashMap, then define it like `public void yourFunc(Map hashMap) {}` – Dmytro Rostopira Jul 27 '16 at 10:29
Iterabile<> is underline in red – markella Jul 27 '16 at 10:30
Red underlin can mean anything, if there is nothing after method declaration (no {}) - this will be underlined. You must learn to read error messages before asking – Dmytro Rostopira Jul 27 '16 at 10:35
public void meMap( Map hashMap ) {} this is my function and arguments are underline in red – markella Jul 27 '16 at 10:37
@markella you can't make same names for function and variable – Dmytro Rostopira Jul 27 '16 at 10:39
as object of hash map " HashMap meMap = new HashMap(); " – markella Jul 27 '16 at 10:39

You just don't know, what you are doing, nobody can help you – Dmytro Rostopira Jul 27 '16 at 10:40
i want pass to another function the hash map...i want iterate it into another function – markella Jul 27 '16 at 10:41

You know what mean "iterate"? And red underline can mean about 10 kinds of error - hover mouse over it and read – Dmytro Rostopira Jul 27 '16 at 10:44
