Enumeration
methods that are used on collections and may be replaced with equivalent
Iterator
constructs.
Example:
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 = iterator.next();
}
