As documented in Enumeration 's Javadoc, you should favor the Iterator interface over Enumeration.
Iterator offers a similar contract to Enumeration with the addition of a method for removal and shorter method names.
Noncompliant code example
public class MyClass implements Enumeration { // Noncompliant
/* ... */
}
Compliant solution
public class MyClass implements Iterator { // Compliant
/* ... */
}
