Suppose I have a Map:
Map<String, MyClass> myMap = new HashMap<String, MyClass>();

I know there is only 1 key/value pair in it. I don't know or care what the key is, but I want to get the value. What's the best way to do this?

I you really know that there is one value you can try:
MyClass value = myMap.values().iterator().next();
