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 programs is essential.

Modules count towards OU qualifications

OU qualifications are modular in structure; the credits from this undergraduate module could count towards a certificate of higher education, diploma of higher education, foundation degree or honours degree.

Credits

Credits

  • Credits measure the student workload required for the successful completion of a module or qualification.
  • One credit represents about 10 hours of study over the duration of the course.
  • You are awarded credits after you have successfully completed a module.
  • For example, if you study a 60-credit module and successfully pass it, you will be awarded 60 credits.

Study level

Across the UK, there are two parallel frameworks for higher education qualifications, the Framework for Higher Education Qualifications in England, Northern Ireland and Wales (FHEQ) and the Scottish Credit and Qualifications Framework (SCQF). These define a hierarchy of levels and describe the achievement expected at each level. The information provided shows how OU module levels correspond to these frameworks.

What you will study

In the object-oriented view of software, programs are considered collections of objects that interact using each other’s methods and results. These ideas are at the forefront of modern software development.

Throughout the module, you’ll 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 emphasises visualisation and interaction techniques that encourage experimentation and exploration.

The module takes an ‘objects first’ approach to teaching; you start seeing and interacting with objects from the beginning, supported by BlueJ features that allow you to learn the principles of object construction and method calling.

You’ll soon start using Java code and syntax to edit provided practical examples, such as a ticket machine, a digital clock, and a program that draws simple graphics. Initially, you’ll add minor functionality to the provided projects and experiment with their facilities.

The module continues the teaching about fundamental object-oriented ideas by investigating:

  • how to control the initial state of newly created objects
  • different kinds of variables and methods in Java
  • different kinds of data, including primitive and object types
  • inheritance hierarchies and their impact on code reuse
  • overriding methods and polymorphism
  • abstract classes and interfaces
  • file input and output.

Along the way, you’ll learn about Java structures for selection and iteration and more about some of the core Java library classes. We introduce you to ideas about writing Java code in a good style and using appropriate design, as well as about different kinds of errors you will encounter and how to deal with them.

As you go on, you’ll develop increasingly complex object-oriented projects from scratch, using the BlueJ IDE, and better understand the more complex examples in the textbook. 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.

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’ll get help and support from an assigned tutor throughout your module.

They’ll help by:

  • marking your assignments and offering detailed feedback to help you improve
  • providing individual guidance, whether that’s for general study skills or specific module content
  • guiding you to additional learning resources
  • facilitating online discussions between your fellow students in the dedicated module and tutor group forums.

Online tutorials run throughout the module. Where possible, we’ll make recordings available. While they’re not compulsory, we strongly encourage you to participate.

Assessment

The assessment details for this module can be found in the facts box.

Future availability

Object-oriented Java programming (M250) starts once a year – in October.

This page describes the module that will start in October 2025.

We expect it to start for the last time in October 2027.

Regulations

As a student of The Open University, you should be aware of the content of the academic regulations which are available on our Student Policies and Regulations website.

Course work includes:

3 Tutor-marked assignments (TMAs)
Examination


Entry requirements

You need to be familiar with basic programming concepts – check if you’re ready for M250, with our self-assessed quiz.

You’d normally be prepared by completing OU level 1 study as part of one of our computing and IT qualifications. For this module, we recommend that you’ve passed Introduction to computing and technology 1 (TM111) and Introduction to computing and information technology 2 (TM112); or their predecessor TU100. Alternatively, you should be familiar with two other programming languages such as Scratch and Python.

Can you study an Access module for free?

Depending on eligibility and availability of places, you could apply to study your Access module for free.

To qualify, you must:

  1. be resident in England
  2. have a household income of not more than £25,000 (or be in receipt of a qualifying benefit)
  3. have not completed one year or more on any full-time undergraduate programme at FHEQ level 4 or above or successfully completed 30 credits or more of OU study within the last 10 years

How to apply to study an Access module for free

Once you've started the registration process, either online or over the phone, we'll contact you about your payment options. This will include instructions on how you can apply to study for free if you are eligible and funded places are still available.

If you're unsure if you meet the criteria to study for free, you can check with one of our friendly advisers on +44 (0)300 303 0069, or you can request a call back.

Not eligible to study for free?

Don't worry! We offer a choice of flexible ways to help spread the cost of your Access module. The most popular options include:

  • monthly payments through OUSBA
  • part-time tuition fee loan (you'll need to be registered on a qualification for this option)

To explore all the options available to you, visit Fees and Funding.

What's included

The module uses a text book (Objects First with BlueJ, by Barnes and Kölling), which will be provided in print and ebook versions. This is supplemented by a range of online materials provided on the module website including OU produced Chapter Companions, supplements, software, programming activities, student forums and a study planner.
