Java For COBOL Programmers

Course Number: 559-JK
Recommended Duration: 5 days

Intended Audience
Experienced COBOL programmers.

Course Overview
COBOL programmers will learn Object-Oriented programming skills and the use of the Java language.

Objectives
Participants will learn object oriented basics, and how to create, test, and deploy programs using the Java language. The course focuses on differences and similarities between the COBOL and Java environments. Students will write applications, servlets, and JSPs as part of the hands-on exercises. Upon request coverage of the locally available IDE (e.g. Eclipse, IBM Rational Application Developer (RAD), JDeveloper, etc.) may be added.

Prerequisites
Students must have programming experience. Experience with text editor, manipulating files and directories, and using a browser are required.
