Description

This course will introduce a person who has programmed in a procedural language (COBOL) to the basics of developing OO applications in Java using an IDE (e.g. VisualAge for Java). This class helps the procedural programmer make the transition into OO programming in Java, and facilitates the student to proceed to a Java programming fundamentals course which will enable the student to code in Java (and prepares the student for the Sun Java Programmer certification).

Audience

Programmers who have experience with a procedural language (e.g. COBOL) who wish to transition into Java programming.

Prerequisites

knowledge of one other programming language and Object-Oriented concepts as covered in OB00 - Object Oriented Introduction.

Objectives

o List the similarities and differences between procedural applications and Java applications
o Compare and contrast single-tier, client-server and multi-tier applications
o List the characteristics of a distributed application
o Compare/contrast Java and procedural (e.g. COBOL) syntax
o Explain and use in a basic Java program
- Primitive types, object variables
- Data types
- Operators
- Control and flow statements
o Develop, compile and run simple Java programs using an IDE (e.g. VisualAge for Java)
o Explain and use the following within the context of an OO application using Java
- Classes and methods
- Constructors and how to instantiate objects
- How to send messages to an object
- Inheritance and containment
- Abstract classes
o Explain the basic concepts of distributed Java technology
