Java Development for Mainframe Programmers

Course:  JAVA101
Duration:  5 Days
Level:  I
Course Summary

This class teaches experienced Mainframe programmers how to utilize the structure and syntax of the object oriented Java programming language for both general business and Internet programming applications. The student will learn how 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. Java syntax will be compared to COBOL along with tools and techniques used on the Mainframe.

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 Fundamentals course instead of this course.
