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:
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.
This module provides a basis for further study of Java programming and introduces you to many (but not all) of the concepts that the Java Certified Programmer and Java Certified Associate exams test.
You’ll get help and support from an assigned tutor throughout your module.

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.
There may be extra costs on top of the tuition fee, such as set books, a computer and internet access.
If your personal income is £25,000 or less, or you’re on certain benefits, you could qualify for a grant and OU top-up funding to cover 100% of your course fees. Apply online at the same time as you register on your module.

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:
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.

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.
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.
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.
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).
We know that sometimes you may want to combine payment options. For example, you may get support from your employer to pay part of your tuition fee and pay the remainder by credit or debit card.
