If you do not want to use the command prompt, then this step is not needed (and setting the PATH variable is not needed for any of the following steps).
#JGRASP JAVA DEVELOPMENT KIT HOW TO#
How to do this is explained in Step 5 of Sun's installation instructions.
So you may want to set the Windows PATH variable to include the Java JDK.
#JGRASP JAVA DEVELOPMENT KIT FULL#
If you want to work with Java from the command prompt, using full path names can be inconvenient. In the last step we used the "full path name", c:\j2sdk1.4.1_04\bin\javac, at the command prompt for the Java compiler javac (and similarly for the Java virtual machine, java). Compile Hello.java with the following command.Īfter the program compiles, run the program with the next command. At the command prompt, use the cd command to move to the directory where you stored the file Hello.java. You should get a "usage message" back from the Java compiler. At the command prompt, enter the following command. Use the Start Menu to start up a "Command Prompt" window. If you want to, you can test your JDK installation. Sun's JDK 1.4.1 Documentation Installation Instructions Sun's JDK 1.4.1 HTML documentation download Move the docs directory to be a sub-directoy of the directory C:\j2sdk1.4.1_04 which was created by the installer in the previous step (the last two digits in this directory name are the "version number" of the JDK). The temporary directory will contain a sub-directory called docs.
#JGRASP JAVA DEVELOPMENT KIT ZIP FILE#
Unzip the zip file into a temporary directory. Download this file from the link at the end of this paragraph. The HTML version of the documentation comes in a zip file (that's why you need WinZip) called j2sdk-1_4_1-doc.zip. But if you want the HTML version, read on. Later in this page I will show you a better version of the documentation to install. But the HTML version of the documentation is large (about 180MB installed) and not easy to use.
#JGRASP JAVA DEVELOPMENT KIT INSTALL#
If you want the HTML version of the documentation, then you need to install that separately. The JDK does not come with any documentation. (It is probably a good idea to print out these instructions before installing the JDK.) To install the JDK, follow the installation instructions from Sun's web pages. The JDK 1.4.1 installer is 36 MB, so expect the download to take several hours using a modem. That will take you to a page where you can download an installation program.
You want to download the "Windows (all languages, including English) SDK" that is second from the top under the heading "Download J2SE v 1.4.1_04". Use the link at the end of this paragraph to go to Sun's download page. Download the Windows version from the WinZip Download Page follow the instructions on that page to install WinZip. If you do not have the program WinZip already installed on your home computer, then you should install it first. The first part is installing the Java development kit (JDK) on the computer and the second part is installing jGRASP. There are roughly two parts to this installation. The steps below tell you how to install this programming environment along with jGRASP. We will be using release 1.4.1 of the Java 2 Standard Edition (J2SE) development kit. This page describes how to install jGRASP and get started with using it.īefore you can install jGRASP, you must install a Java JDK. JGRASP is a freeware development tool for writing Java programs that was specifically designed for educational use.
