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. Students will learn: Object oriented concepts Java syntax and control structures Data types and expressions Packages, classes, objects and methods arrays String handling Exception handling Inheritance and polymorphism Input and output stream processing GUI programming concepts Course Prerequisites: Familiarity with and experience using COBOL or any procedural programming language.

Prior to each class they examine the geographical location of the enrolled students and then select a venue that will provide most convenient overall access for the students. Classes are held in hotel conference rooms and exact location is determined 2 weeks prior to the course date.
