What is BlueJ and why use it?
BlueJ is a Java development environment that was created by the BlueJ team at Deakin University, Melbourne, Australia, and the University of Kent at Canterbury, UK. It is designed specifically for teaching and learning object-oriented programming with Java.
BlueJ has a simple and user-friendly interface that allows you to create, edit, compile, run, test, and debug Java programs easily. It also has interactive features that let you create and manipulate objects, invoke methods, and evaluate expressions in real time. It also has a textbook and teaching resources that cover the fundamentals of Java programming and object-oriented design.
What are the prerequisites for installing BlueJ?
Before you can install BlueJ on your Windows 7 computer, you need to make sure that you have the following components:
A 64-bit Windows 7 or later operating system. BlueJ does not support 32-bit Windows systems.
A Java Development Kit (JDK) version 11 or later. The JDK is a software package that contains the tools and libraries needed to develop and run Java programs. You can download the JDK from the official Oracle website. You can choose either the Oracle JDK or the OpenJDK, which are both compatible with BlueJ.
An OpenJFX Software Development Kit (SDK) version 11 or later. The OpenJFX SDK is a software package that contains the libraries and tools needed to develop and run Java applications that use graphical user interfaces (GUIs). You can download the OpenJFX SDK from the Gluon website. You need to choose the version that matches your JDK version.
Once you have downloaded these components, you need to install them on your computer and set up the environment variables accordingly. You can follow the instructions on the respective websites for more details.

After you have installed the prerequisites, you can download BlueJ for Windows 7 from the BlueJ website. You will see two options for downloading BlueJ:
The MSI installer, which is a file that will guide you through the installation process. This option is recommended if you want to install BlueJ for all users on your computer and have it integrated with your system.
The standalone zip file, which is a file that contains all the files needed to run BlueJ. This option is recommended if you want to install BlueJ for yourself only and have it portable on a USB drive or a cloud storage service.
