Learn Java from Scratch - A Beginner's Guide - Step 03 - List Interface - Immutability and Introduction of Implementatio

The video tutorial explores the concept of immutability, explaining that certain classes like String and BigDecimal are immutable, meaning their values cannot be changed once created. It contrasts this with mutable lists, which can be modified, and demonstrates how to create mutable lists using ArrayList, LinkedList, and Vector. The video also covers basic operations on these lists, such as adding elements, and concludes with a prompt for viewers to experiment with these concepts further.
