COMP 110: Introduction to Programming. jGRASP

Getting Started with jGRASP

Uninstall

If you previously installed 2 SDK, SE v1.4.2_15 you will need to uninstall this software. Go to Start -> Control Panel -> Add or Remove Programs and click on Java 2 SDK, SE v1.4.2_15. Click remove. A box will appear, click Yes to continue uninstalling the software. You will then have to reboot your computer. Once you have successfully uninstalled Java 2 SDK, SE v1.4.2_15, proceed with the rest of the instructions.

Installation

To properly install jGRASP, you'll need to download and install both jGRASP 1.8.6_01 and the Java Software Development Kit (SDK).

Java SDK

Download jdk-6u3-windows-i586-p.exe to your Desktop (It's a big file, 65MB). Double-click on the file once it's on your Desktop, and the script will take you through the steps for installing the Java SDK.

Steps

In the License dialog box, choose "I accept the terms..." and click Next
In the Custom Setup dialog box, you don't need to make any changes, so just click Next
In the Browser Registration dialog box, you don't need to make any changes, so just click Install
The installation will begin, and a progress bar may not seem to show progress.
It may take several minutes, with an occasional popup box.
When it's done, you should see a dialog box that says "The InstallShield Wizard has successfully installed Java 2 SDK". Click Finish.
You should restart your computer.

jGRASP 1.8.6_01

Download jgrasp186_01.exe to your Desktop. Double-click on the file, and the script will take you through the steps for installing jGRASP.

Steps

In the Welcome dialog box, click Install.
In the jGRASP License dialog box, click Agree.
In the Choose Components dialog box, you don't need to make any changes (Standard), so just click OK.
In the Choose Installation Location dialog box, you don't need to make any changes, so click OK
In the second Choose Start Menu Folder dialog box, you don't need to make any changes, so click OK.
You will be presented with a dialog showing file associations jGrasp would like to make. Deselect all of them except the one that askes about .java and .jav files.
Once you've answered all of the dialog boxes, the installation will begin.
On my laptop and window showing the install of "installfonts.exe" froze, so after a while I killed it.
You will then see a dialog box that says "jGRASP has been installed successfully". Click OK.

When you have completed the installation, you should find the jGRASP icon on your Desktop. jGRASP should also be listed on the Start Menu, under All Programs.

Once you have successfully installed the Java SDK and jGRASP, you can delete jgrasp186_01.exe, j2sdk-1_4_2_15-windows-i586-p.exe, and Java Web Start from your Desktop.

Starting jGRASP the First Time

Double-click on the jGRASP icon on your Desktop to start jGRASP. You will probably get a message saying that there is a newer version of jGRASP available online. It's ok, just ignore that message.
There are a couple of settings that you need to change the first time you run jGRASP. You only need to follow these steps once.

Go to the Settings menu and highlight Look and Feel>. A sub-menu will pop up. Select Windows. This will make jGRASP look like a normal Windows program.
Go to the Settings menu and highlight Compiler Settings>. A sub-menu will pop up. Select Workspace. A dialog box will open. After following the steps below, the dialog box should look like this picture.
- Choose the Languages tab at the top of the dialog box.
- In the drop-down box next to "Language:", choose Java.
- Choose the Environment tab under the "Language:" drop-down box.
- Click on "jdk (integrated debugger, HotSpot VM, prefer JDK compiler) - generic" so that it's highlighted.
- Click the Use button to the right of the list.
- Click OK.

Before continuing, you should read the Getting Started chapter of the jGRASP documentation through 2.4. It's big, but there are lots of pictures :-).
