This video tutorial explains how to enhance a bank account class by adding methods for deposit and withdrawal. It covers the implementation of these methods, emphasizing the importance of parameters and balance updates. The tutorial also demonstrates how to test these methods by modifying the code and validating transactions. The video concludes with a practical example of running the code to ensure the methods work as expected.
