Anytime you have a collection of things you will need some mechanism to systematically step though the items in that collection. As an everyday example, consider the television remote control ...

Java’s collections like arrays and lists are foundational building blocks. Functional programming techniques are at times the ideal way to work with these collections.

There will be a lot of code examples here, which will show how to change the code that uses the standard Java collections and streams, to code that uses the Eclipse Collection framework.

Java's collections framework has long needed a collection type that represents a sequence of elements with a defined encounter order and a uniform set of operations that apply across such collections.

However, there are collection classes in Java that act like a Java array but resize themselves automatically. Any class that extends the List interface expands dynamically. Java arrays do not expand ...
