Enumeration can be iteration

Reports calls to Enumeration methods that are used on collections and may be replaced with equivalent Iterator constructs.


Enumeration<String> keys = map.keys(); while (keys.hasMoreElements()) { String name = keys.nextElement(); }

After the quick-fix is applied:

Iterator<String> iterator = map.keySet().iterator(); while (iterator.hasNext()) { String name =; }
