Java Programming for COBOL Programmers

Java Programming for COBOL Programmers
Duration: 5 days
Audience
Prerequisites
Application Developers
System Designers
Experience with at least one structured programming language
Description
This course is specially designed for COBOL programmers seeking to design and develop applications using the Java 2 Standard Edition (J2SE). Based on InferData's well-received training methodologies, the course provides for a rapid and efficient transition to object-oriented software development using J2SE. The attendees are expected to be familiar with COBOL or some other structured programming language. Experience with object orientation would be helpful but is not required.This five-day course covers topics in object-orientation, the basics of programming using Java, including syntax, compilation, packaging and deployment. The J2SE class library and architecture are also covered as well as multi-threaded programming in Java. Other topics covered include concepts in "Interface based design for de-coupled and concurrent development". The Java class libraries covered include: Java utilities, input and output (I/O), web based client development using Java "Applets", a brief introduction to graphical user interfaces development using the Java Swing library, and an introduction to the Java Database Connectivity (JDBC). Where applicable, all the concepts will be conveyed in a way such that COBOL programmers can relate to their familiar COBOL counterparts.This course consists of a large number of fully worked out example code illustrating various concepts introduced during the course. The concepts are further reinforced through the use of well-crafted exercises at appropriate points throughout the course.
