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.

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 on visualisation and interaction techniques providing a highly interactive environment that encourages experimentation and exploration.

The module takes an ‘objects first’ approach to teaching; you start seeing and interacting with objects from the beginning. BlueJ features 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 of 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

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

Marking your assignments (TMAs) and providing detailed feedback for you to improve.
Guiding you to additional learning resources.
Providing individual guidance, whether that’s for general study skills or specific module content.
Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

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.

Additional Costs

Study costs

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

If your income is not more than £25,000 or you receive a qualifying benefit, 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.

Employer sponsorship

Studying with The Open University can boost your employability. OU courses are recognised and respected by employers for their excellence and the commitment they take to complete. They also value the skills that students learn and can apply in the workplace.

More than one in ten OU students are sponsored by their employer, and over 30,000 employers have used the OU to develop staff so far. If the module you’ve chosen is geared towards your job or developing your career, you could approach your employer to see if they will sponsor you by paying some or all of the fees.

Your employer just needs to complete a simple form to confirm how much they will be paying and we will invoice them.
You won’t need to get your employer to complete the form until after you’ve chosen your module.

Credit/debit card

You can pay part or all of your tuition fees upfront with a debit or credit card when you register for each module.

We accept American Express, Mastercard, Visa and Visa Electron.

Mixed payments

We know that sometimes you may want to combine payment options. For example, you may wish to pay part of your tuition fee with a debit card and pay the remainder in instalments through an Open University Student Budget Account (OUSBA).

Please note: your permanent address/domicile will affect your fee status and, therefore, the fees you are charged and any financial support available to you. The fee information provided here is valid for modules starting before 31 July 2025. Fees typically increase annually. For further information about the University's fee policy, visit our Fee Rules
