“…It provides a graphical interface for the specification of classes and their relationships, an integrated editor and compiler and a symbolic debugger. In addition, the Blue environment provides an interactive testing facility [4] which allows the interactive creation of objects of any class and calling of the methods of these objects. It is this testing facility which allows the delay in teaching I/O.…”

One of the major difficulties with teaching the first programming course is input/output. It is desirable to show students how to input data and output results early in the course in order to motivate the students and so that they can see the results of their programs. Output is also a useful tool for testing programs. However, in most programming languages input and output are esoteric and the techniques for performing input and output must be learnt by the students at an early stage, precisely when they are trying to understand the basics of programming. We argue that input/output operations need not be taught in the early stages of a course if the language environment provides appropriate tools for testing programs. This assertion is demonstrated by reference to the Blue objectoriented language and environment.

Visualization is a useful tool in many areas of computer scil ence education. This paper describes the use of visualization in the introduction of object-oriented concepts. A Java application has been developed that allpws the user' to interact with a visualiza.tion of any Java class through the instantiation of objects, the movement of those objects around the class environment, and the activation of class methods. The user may also move conveniently between classes in this visualization.This Object Visualizer is useful for classroom demonstration, individual student use in the laboratory,. and class debugging and testing.
