How to Install Java 1.6 and BlueJ

To install Java 1.6, you have to first download it from the Sun website. You should go to

http://java.sun.com/javase/downloads/index.jsp

You will see:

You should choose the version of JDK 7 with the Java SE Development Kit (JDK), which includes the Java Runtime Environment (JRE) and command-line development tools. When you click on this download button, you will see the following page:

Then click on Accept License Agreement and choose the appropriate version that you want. If you are installing this on a Linux system, etc., then choose the appropriate version. Notice that there is no Mac version. This is because Java comes pre-installed on all Mac’s. If you do not have Java on your Mac, you can download the Window’s version. You then must install Windows on your computer.

If you have Windows’s on your PC, then choose either the Windows x86 if you have a 32-bit computer.

Choose Windows x64 if you have a 64 bit computer. If you bought a computer in the last year, then you have a 64-bit computer. If you are not sure, then download the x86 version which will work on either one.

After you do this, you will see the following choice:

You should save the file to your desktop. Then double-click on the file and let it be executed if prompted by your computer asking if it is safe. You will see:

After clinking on Next> you will see:

Here it is asking you where to install it. The default is the

C:\Program Files\java\java1.7.0, which is what I chose. You can choose any place you want, but it is best to keep it on the C: drive.

Then just follow the prompts choosing the default values. It will take a couple of minutes to install. When you finish you will be prompted to register your software to get updates, etc.

It is recommended to register but it is not necessary.

Next you want to install BlueJ. Note, you must install Java before BlueJ, as BlueJ has a java executable for installation. Before you download “BlueJ” , you must create a folder called “BlueJ”. Where you install it is up to you. I have installed mine inside the “Java1.7” folder.

After creating the folder, you will now need to download “BlueJ”. To do this, open up your internet browser and go to the website of “www.bluej.org. It will look like:

Click on the “Download” link on the left hand side of the page(below “About BlueJ”), to get:

Choose the one that you need, and download it. (Since I am installing this on a PC, I choose the “bluejsetup-305.exe” file”.) You will be prompted by a popup directory window, and choose the “Bluej” folder to where it is to be saved. You will also be prompted of where you want the short-cut to be installed. You can leave it in the “BlueJ” folder, but be sure to click the yes for a short-cut icon on the desktop:

Then click on the “Install” button when prompted and you will be done.

If you close the windows, on your desktop you will see a “BlueJ” icon with a bluejay as its pictograph:

If you double-click on the BlueJ icon you will see:

This is how one starts a Java project in BlueJ.
