This workshop provides a visual manner in which to introduce OOP using Java. The Gogga class is a simple graphical tool which provides a Gogga object that can, in essence, move (), turnLeft () and turnRight (). Using these methods, simple rectangular shapes can be drawn on an output grid. The Gogga class also includes other methods to change the colour and the thickness of the lines drawn as well as setting and returning the position of any Gogga object. Since the Gogga class only provides basic movements for objects instantiated from it, objects of classes that inherit from the Gogga class will have the basic movements as well as more functionality provided by the new inheriting classes. Length required: 90 minutes Requirements: Delegates need to have a fundamental knowledge of programming in any high-level language, including a fair understanding of the use of loops and subprograms. Structure of the workshop: 1. Introduction to a simple Java program that uses an object of the Gogga class to draw a square. Exercise to draw a rectangle in Java with a Gogga object. The exercise is extended to include colour and lines of different thicknesses. The exercise is further extended to include for loops and methods. 2. A new class RectGogga is created that inherits from the Gogga class. objects of this class are used to draw rectangles of different sizes. Brief explanation of syntax used with inheritance. Exercise to create a new class Pyramid to create objects that draw pyramid shapes of any size. This class is called from a program that will draw pyramids of any sizes. Exercise to draw a house using the new methods in the Pyramid and RectGogga classes.

Today's test environment is more challenging than ever as pressure on increasing quality and meeting time-to-market continue to increase. Because of these recent advances in computer and other technologies, it is becoming evident that a sound foundation in computer networking is critical for success in many kinds of computer-based work and universities must produce graduates with solid foundation in computers and their applications to solve real world problems. One way to achieve this is through interactive learning and teaching through the use of software packages like Lab VIEW (Virtual Instruments) and Java/Visual Basic (object oriented programming). This will also allow the student to have greater interaction with the subject matter and improve his/her skills in the use of number of applied engineering software packages. This paper will discuss design and development of interactive instructional modules for Number Systems, Internet Protocol Addresses, Address Classes, Subnet Masks, and Subnetting using LabVIEWand Visual Basic/Java.
programming large objectoriented systems is a difficult task. With the help of specific programming tools integrated in a uniform programming environment, this task can be facilitated. In this paper, we describe the ...

One of the objectives of the CTRON interface specifications is to promote software-reutilization for real-time applications by standardizing operating system interfaces. Although this approach does improve reusability by improving portability, means for gaining better composability has to be taken into consideration to achieve more advanced reutilization. object oriented programming (OOP) which supports encapsulation, polymorphism and inheritance is an appropriate programming paradigm for improving composability of software-modules. This paper describes how we apply OOP to systems based on the CTRON specifications and mainly describes the C++ class libraries we have been designing. This paper also describes how we evaluate the performance, reusability and portability of programs that use the base class libraries.
