Iteration with the Enumeration class In Java 1.0 and 1.1, the two primary collection classes were Vector and Hashtable, and the Iterator design pattern was implemented in a class called Enumeration.

Java collection framework provides you with the complete architecture of objects. Java frameworks group of objects includes – classes, interfaces, and algorithm.

At the base of the Framework are the interfaces java.util.Collection and java.util.Map. The Collection interface represents just a group of objects, with no particular order or restriction.

The default method role offered by interfaces has given new life to the Java Collections Framework. You might consider this role for your own legacy interface-based libraries.

Let's compare the Java Iterator vs. ListIterator interfaces and find which one makes the most sense in different scenarios. Iterators, ListIterators and Collections In computer programming, a ...
