Description/Agenda
Students Will Learn:
- Object Oriented Concepts
- Java Syntax and Control Structures

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.
