Course Description

This hands on Java Programming course provides experienced COBOL programmers with the ability to utilize the structure and syntax of the object oriented Java programming language for both general business and Internet programming applications. The student is prepared to code, test, and execute Java programs making use of the facilities provided by the language. Because procedural programming uses a different paradigm than object oriented programming, this course concentrates on the application of basic object oriented concepts.

This class is intended for experienced COBOL programmers or programmers experienced in any procedural (non object-oriented) programming language. Students who already understand object-oriented programming techniques should attend the Java Programming course instead of this course.

Course Prerequisites

Familiarity with and experience using COBOL or any procedural programming language.
