Exploring the Computer and Theater Analogy in Programming

This introduction to programming presents a unique analogy between the worlds of computer science and theater. Led by instructor Jason Carter, the course examines how programming languages operate similarly to scripts in a theater, involving components like performers, stagehands, and directors. Through detailed explanations of machine language, source code, and error detection, students will learn about various programming concepts using the metaphor of theatrical performances. The course aims to enhance understanding of programming through this engaging comparison, highlighting the interactivity and structure in both fields.

  11. Computer vs. Theater

  12. Computer vs. Theater

  13. Computer vs. Theater • CPU is fast: can do several performances at one time. • CPU is dumb: no improvisation possible. • Machine language much lower-level than programming language.

  14. Why Java • Modern, modular (object-oriented) language. • Good Error Detection. • Rich Library Embodying Many Good Programming Principles • Can Write Teaching Tool (ObjectEditor)

  15. Java Versions, Dialects & Programming Environment • JDK 1.5+ • Eclipse IDE Programming Environment
