What is object-oriented programming?

Object-oriented programmingis our introduction to data abstraction. We em- phasize the concepts of a data type (a set of values and a set of operations on them) and an object (an entity that holds a data-type value) and their implementation using Java’s class mechanism. We teach students how to use, create, and designdata types.

What is the difference between OOP and C programming?

Programming in such a language is called object-oriented programming (OOP), and it allows computer programmers to implement an object-oriented design as a working system. Languages like C, on the other hand, are procedural, so programming tends to be action oriented. In C, the unit of programming is the function.

What is Java programming?

IN THIS SECTION, OUR PLAN ISto lead you into the world of Java programming by tak- ing you through the basic steps required to get a simple program running. The Java system is a collection of applications, not unlike many of the other applications that you are accustomed to using (such as your word processor, email program, and internet browser).

Object-Oriented Concepts - Presentation Topics

The time-limit for each presentation is strictly 20 minutes. Half of each group"s members must present on OO Concepts and the other half on Design Patterns (still to be published). For a group of five members, three members will present on one topic and two on the other. All presenters for a particular topic will receive the same mark. Presentations need to beinteractive, in other words, the class needs to be involved in some activity or exerciseto illustrate the topic that you are explaining. This implies that your actual talk-time is much less than 20 minutes! Please email your presentations, in PDF or Powerpoint format, to me by 10:00 on the presenta- tion day (joshua@jcse.org.za). The following topics are intended to both highlight and revise fundamental object-oriented conceptsandassociatedconcepts. Youmayassumethatyouraudiencehasabasicunderstanding of Object-Oriented Programming (OOP) which needs refreshing. Most topics have a number of questions which should be dealt with in your presentation, but your presentation should not be confined by these questions.

1 Memory Management

Whose responsibility is memory management in C++, Java and C# (the programmer"s or the run-time environment)? What is the difference between deterministic and non-deterministic object destruction? How is memory management handled in C ++andC# or Java?

What is garbage collection?

Give a code example in C ++andin Java or C#.

2 Value and Reference Semantics

How are objects copied by default in different languages (C++, Java, C#) and is it possible to change this default behaviour? What is the difference between value types and reference types? What is the difference between passing by reference and passing by value and what are the implications? What does the "new" keyword do (when instantiating a new object)? Give code examples to illustrate some of the above points. 1
