More clarity on AbstractList implementation in class_extension/abstract_classes #183
Description
https://javabook.mccue.dev/class_extension/abstract_classes
id probably add a sentence or example to point out that the FiveAndSeven list now got hands on a lot of methods for free coming from AbstractList.
like, u sorta mentioned it in the comment but i think using two or three more methods in the main example down there (or adding an extra sentence) to point this out more would be useful
