At the end of the video, I run through all steps in real-time to show that it takes about 5 minutes. This is a neat little project because it combines many powerful and useful techniques such as: ⚪️ JShell for rapid prototyping/scripting of ideas in Java ⚪️ Regular Expressions (regex) for parsing text patterns from virtually any larger text ⚪️ Java Streams/Lambda API for streamlining a processing workflow using the Functional Programming paradigm ⚪️ Java 8 Date/Time API which has a rich & very easy-to-use API for dealing with all aspects of time ⚪️ How to break up a long line of code in JShell into multiple lines without triggering execution Additionally, I show Streams concepts graphically to help visualize how they're working.
