What is method overloading

Lecture 9 - Write Maintainable Code
Why meeting the functional requirement is not enough, specifically if you are writing your software using object oriented paradigm
How we can simplify our code while achieving same functionality
How shifting the domain logic to related classes help in better design and less code
How we decompose our logic to multiple methods to simplify code and improve its readability
Why excellence is not an option if you want a better career in software e.g. Remote Jobs, Technology Business and Freelancing etc.
How better code help us to manage complexity
Focus on details is life long skill and help in other areas of life
