iterating over elements of a HashMap

Asked by DJ_AM_Juicebox in Java Programming Language

Tags: hashmap, iterating, over

Hi,

I made a HashMap<String, Integer>. I want to iterator over all elements.

for (Iterator it = m_Table.values().iterator(); it.hasNext();) {
    Map.Entry entry = (Map.Entry)it.next();
    String strKey = (String)entry.getKey()
    Integer nData = (Integer)entry.getValue() ;
}

This causes a runtime exception though... what's the right way to do it?
