Abstract:
Computer programming has been a science for approximately 50 years. It this time there havebeen two major paradigm shifts that have taken place. The first was from “spaghetti code” to structured programs. The second paradigm shift is from procedural programs to object oriented programs. The change in paradigm involves a change in the way in which a problem is approached, can be solved, as well as a difference in the language that is used.
The languages that were chosen to be studied, are COBOL and Java. These programming languages were identified as key languages, and the languages that software development are the most reliant on. COBOL, the procedural language for existing business systems, and Java the object oriented language, the most likely to be used for future development.
To complete this study, both languages were studied in detail. The similarities and differences between the programming languages are discussed. Some key issues that a COBOL programmer has to keep in mind when moving to Java were identified.
