    I was trying to add the contents of one HashMap (a) into another HashMap (b).

    I found it simple to iterate through HashMap a this way:

    a.forEach((k, v) -> b.put(k, v));
    

    You can manipulate my example to do what ever you want on the other side of "->".

    Note that this is a Lambda expression, and that you would have to use Java 1.8 (Java 8) or later for this to work. :-)
