Java for COBOL Programmers

Recommended Duration:
5 Days
Java SE 8
(suitable for earlier Java versions)
COBOL programmers will learn Object-Oriented programming skills and the use of the Java language. 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.
Experienced COBOL programmers.
Students must have programming experience. Experience with text editor, manipulating files and directories, and using a browser are required.
