Java Programming for the IBM Enterprise
Duration
7 hours
Overview
This course is intended for experienced Mainframe Programmers, particularly COBOL programmers who need to be able to use Java as an alternative language to COBOL and to use Java to extend enterprise systems to the Internet. A breakdown of code commonly used with Java programming is supplied, providing equivalent COBOL examples along the way.
Audience
Experienced Mainframe Programmers, particularly COBOL programmers
Prerequisites
Knowledge and experience of a procedural mainframe programming language, preferably COBOL. An understanding of Object Orientation, Java structures, and environments.
Objectives
- After completing this course, the student will be able to:
- Understand Java as an alternative language to COBOL. (Java structures will be compared and contrasted to their COBOL equivalents.)
- Use Java to extend enterprise systems to the Internet.
