Inconsistent HashMap between classes - Java

Vote count:

0

I have class A which has a HashMap as a public field:

public static final HashMap<String, String> map = new HashMap<String, String>();

And in class B (which is multi-threaded, implements Runnable), I do some puts.

Now, in class C I'm tryin to read from the map. But the changes to the map are not reflected in class C.

I am not storing any references anywhere, but I access the map through the class name.

A.map.put("hi", "hello");     //in thread B
A.map.get("hi");              //in thread C

And I am sure that I call get() after I call put()..

I thought there could be a problem with concurrency and I changed the HashMap to a Hashtable but it is still the same..

Am I missing somethiing here?
