COMP 14: Introduction to Programming. jGRASP

Getting Started with jGRASP


To properly install jGRASP, you'll need to download and install both jGRASP 1.8.3 and the Java Software Development Kit (SDK).

Java SDK

UPDATE Download Java SDK 1.5.0 Update 4 from sun:
There are differences between versions 1.5.0 and the older 1.4.2. The second edition of Malik's book relies upon some of the new features in 1.5.0.


jGRASP 1.8.3

Download jgrasp183.exe from the website. There are both Windows and Mac options (Mac users will need administrator privelages).
Windows: Double-click on the .exe file, and the script will take you through the steps for installing jGRASP.
Mac: Double click on the .tar.gz, find the jGrasp183.pkg file and double click on it.


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 jgrasp183.exe, j2sdk-14203.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. Before continuing, you should read the Getting Started chapter of the jGRASP documentation.

These guidelines have been borrowed from Kelly Ward ( and Michele Clark Weigle (, previous instructors of Comp14.
