Object-oriented Java programming

This module 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 object-oriented software development. Some experience in writing computer programmes is essential - see the Am I ready? section.

What you will study

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 module 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 basic object-oriented principles, before you attempt Java syntax or source code.

Throughout the module you will use BlueJ, an integrated development environment (IDE) specifically developed for teaching and learning object-oriented programming. BlueJ is used worldwide and is easy to use. It places special emphasis on visualisation and interaction techniques to provide a highly interactive environment that encourages experimentation and exploration.

In the first part of the module you will interact with micro-worlds of graphical objects to explore basic object-oriented ideas. You will soon start using Java code and syntax to write 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. You will be expected to write short methods (the smallest units of code in Java) to specification.

The module 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 together with techniques for error handling, program design and debugging. 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.

You will then be introduced to a subset of the Java collection classes, and related issues such as ordering and sorting. You are guided to apply the knowledge you gained from the first parts of the module, 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.

The last part of the module 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. Both of these techniques are useful in larger scale programs.

Vocational relevance

This module provides you with a basis for further study of Java programming and introduces you to many (but not all) concepts that are tested by Java Certified Programmer and Java Certified Associate exams.

Teaching and assessment

Support from your tutor

You will have a tutor who will help you with the study material and mark and comment on your written work, and whom you can ask for advice and guidance. Throughout your study you will use email and online forums to keep in touch with your tutor and other students in your tutor group. We may also be able to offer face-to-face group tutorials that you are encouraged, but not obliged, to attend. Where your tutorials are held will depend on the distribution of students taking the module.

Contact us if you want to know more about study with The Open University before you register.

Assessment

The assessment details for this module 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.

Future availability

Object-oriented Java programming starts once a year – in October. This page describes the module that will start in October 2018. We expect it to start for the last time in October 2023.

    Additional Costs

    Study costs

    There may be extra costs on top of the tuition fee, such as a laptop, travel to tutorials, set books and internet access.

    If you're on a low income you might be eligible for help with some of these costs after your module has started.

    Ways to pay for this module

    Open University Student Budget Account

    The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

    You pay the OU through OUSBA in one of the following ways:

    • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
    • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

    Joint loan applications

    If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

    As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
