while (foo.hasMoreElements()) {
Object key = foo.nextElement();
Object val = uiDefaults.get(key);
System.out.println("[" + key.toString() + "]:["

}
How should I fix this?
By doing as it says:
Enumeration<Object> foo = uiDefaults.keys()
Or have a look at the API of UIDefaults, to see whether it is some more
specific Enumeration (I suppose not).
It's not. UIDefaults is a subclass of Hashtable<Object,Object> (yet
another example of inappropriate use of inheritance instead of composition).
