Summary
This course teaches the fundamental ideas behind the object-oriented approach to programming; through the widely-used Java programming language. Concentrating on aspects of Java that best demonstrate object-oriented principles and good practice, you’ll gain a solid basis for further study of the Java language, and of object-oriented software development. You’ll need to be confident using a Windows-based PC, and have some experience of writing small programs, such as that gained through study of Block 2 of M150. You should also be able to write short explanations of technical ideas in your own words, and be able to communicate with others electronically.
Course content
In the object-oriented view of software, programs are considered to be collections of objects that interact by sending messages to one another and reacting to the answers to those messages. These ideas are at the forefront of modern software development.
The course takes an ‘objects first’, approach to teaching: you start seeing and interacting with graphical objects right from the very start. This is achieved by working within innovative and engaging micro worlds that allow you to learn some basic object-oriented principles, before having to get to grips with Java syntax or source code.
To facilitate the teaching of Java, the course makes use of BlueJ, an integrated development environment (IDE) specifically developed for teaching and learning object-oriented programming. BlueJ is used worldwide and is designed to be easy to use and places special emphasis on visualisation and interaction techniques to provide a highly interactive environment that encourages experimentation and exploration.
As you study the course, you will be using email, computer conferencing and the World Wide Web for communication with the University, your tutor and other students. You may also have the opportunity of attending face-to-face tutorials with your tutor and other students in your tutor group.
You will learn
- the fundamental concepts associated with object-oriented programming (object, class, protocol, hierarchy, inheritance, encapsulation, polymorphism, collaboration, etc.)
- to apply and extend your knowledge of programming concepts within an object-oriented programming context.
In Block 1 you will interact with a micro world of graphical objects to explore basic object-oriented ideas. However, soon you will be getting to grips with Java code and syntax and will begin writing your own simple object-oriented code using the BlueJ IDE. Basic object-oriented concepts such as attribute, state, protocol, class and subclass are introduced, initially through interaction with the micro world, and then in the context of writing Java code. By the end of the block, you will be expected to write short methods (the smallest units of code in Java) to specification.
Block 2 continues the teaching about fundamental object-oriented ideas, by investigating inheritance hierarchies, overriding methods, abstract classes, interfaces, polymorphism, re-use of code, static methods and variables. Along the way, you’ll learn about creating your own classes, about the facilities of Java for selection and iteration, and more about some of the core, provided Java classes. Different kinds of errors are discussed, along with debugging in the BlueJ environment. After discussion of the need to design code, you will be expected to be able to implement to specification a class along with its methods.
Block 3 introduces a subset of the Java collection classes, and related issues such as iteration. You are guided to apply your knowledge from Blocks 1 and 2, along with the new classes being introduced, to increasingly complex programming exercises. The skill of appropriately utilising a provided library of classes (searching for a useful class and method, for example) is explicitly developed in this context, and re-use by composition is discussed.
Block 4 begins by investigating how data is written to and from files in Java and how objects can be made persistent by writing them to file. The block then goes on to discuss software testing in an object-oriented context and the use of the testing tool JUnit. Finally the block puts what you have learnt in this course into the context of software development – a set of activities, stages and techniques which help individuals and teams to write software that meets its users' requirements.
Entry
The course is suitable for students who have taken a Level 1 course involving programming, or who have equivalent programming knowledge. It assumes:
- knowledge of, and facility with, basic programming concepts such as sequence, selection, iteration and data types
- a general familiarity with the basic components and working of a computer
- study skills appropriate to Level 2 study.
If you have any doubt about the suitability of the course, please contact our Student Registration & Enquiry Service.

If you have a disability or additional requirement
Course texts are available in electronic format, and descriptions are available for the diagrams that are used throughout the text. Our Services for disabled students website has the latest information about availability.
If you are a new student, or new to courses using a computer or the internet, you will need to inform us of your particular needs as soon as possible, as some of our support services may take several weeks to arrange. Details of how to do this and our range of support services are described in our booklet Meeting Your Needs which you can download or request from our Student Registration & Enquiry Service.
You can also find information about accessible course materials, financial support and the Disabled Students' Allowance, equipment and other services, on our Services for disabled students website. It also includes our contact details for advice and support both before you register and while you are studying.
Course materials
What's included
Course texts, other printed materials, course software, website, computer conferencing.
Computing requirements
This course includes online computer activities – you can access these using a web browser that can play Flash and Shockwave.
You will need internet access and a computer. If you have purchased a new computer since 2002 it should meet your course computing requirements. Check our Technical Requirements section if your computer is older than this or is otherwise unusual.
Teaching and assessment
Support from your tutor
You will have a tutor who will help you with the course material and mark and comment on your written work, and whom you can ask for advice and guidance. We may also be able to offer group tutorials or day-schools that you are encouraged, but not obliged, to attend. Where your tutorials are held will depend on the distribution of students taking the course. Contact our Student Registration & Enquiry Service if you want to know more about study with The Open University before you register.
Assessment
The assessment details for this course can be found in the facts box above.
You will be expected to submit your tutor-marked assignments (TMAs) online through the eTMA system unless there are some difficulties which prevent you from doing so. In these circumstances, you must negotiate with your tutor to get their agreement to submit your assignment on paper.
