From the official Oracle Javadoc:
NOTE: The functionality of this Enumeration interface is duplicated by the Iterator interface. In addition, Iterator adds an optional remove
operation, and has shorter method names. New implementations should consider using Iterator in preference to Enumeration.
Noncompliant Code Example
public class MyClass implements Enumeration { // Non-Compliant
/* ... */
}
Compliant Solution
public class MyClass implements Iterator { // Compliant
/* ... */
}
