A lot of students end up really being confused by introductory computer science classes, especially with an object-oriented programming language like Java. Don't worry. We're here to help.
Jesse Frush and Andrew Nguyen are students studying computer science at Iowa State University. We have been teaching assistants for Introduction to Object-Oriented Programming (ComS 227) and Data Structures (ComS 228) courses for many semesters.
Although our tutorials follow the structure of the courses and use those as our topics for screencasts and videos, there is no official association whatsoever.
