Although the first computer programs were written in the 1940's, it was only in the 1960's that researchers started seriously studying the human process of computer programming, in an effort to systematize how to write correct, reliable, modifiable programs. The results were presented as a series of ``programming methodologies'' -- Modular Programming, Structured Programming, Object-Based Programming, and most recently Object-Oriented Programming, or OOP -- each of which subsumed the lessons of its predecessor and added new principles for designing ever larger and more complex programs. This semester we'll work in the Java programming language, which was designed for OOP, and which has the added benefit that programs written in Java can use the Internet, and be incorporated into World Wide Web pages, relatively easily.
