Here are the instructions for downloading JDK (Java Development Kit)
and the JCreator IDE (Integrated Development Environment). You may prefer
to download JDK as a step in the downloading of JCreator. Both of these
programs are free.
The JDK bundle, also called the Java SE (Standard Edition) contains
the java compiler (javac) which produces java bytecode; and
contains the JRE (Java Runtime Environment) which in turn
contains the Java Virtual Machine (JVM) which executes the bytecode, i.e.,
runs and interprets the java byte code for your platform. It also contains
the API (Application Programmers Interface). The API consists of many
programs usefull in developing applications.
We say that JCreator is a "thin layer" above the JDK. This means that
it does not contain the compiler or the interpreter (it points to
JDK); but it will enable you to compile, debug and run your programs
by chosing menu options. For instance, if you make a compilation
error, JCreator displays the error messages in a separate window. When you
double click a given error message, JCreator will point to the offending
line in your program. This is very helpful, especially for long
Both of these programs are downloaded in zipped form. In order to
unzip them you need WINZIP. If you don't have it, download it from
DOWNLOADING THE JDK BUNDLE
Again, you may prefer to download JDK as a step in the downloading of JCreator.
However, you may be using a different IDE from JCreator and may have
to download JDK separately. Here's how:
- Go to the javasoft URL:
The JDK instructions change frequently. Here is the current set.
- Under the heading Java SE Downloads click the box with the
Java icon which is simply labeled Java. It's at the left.
- The next window has Download Java SE Development Kit 6u21
and click the DOWNLOAD button.
drag down until Windows is selected. Then hit Continue.
On the next page double click the link
JDK-6u21-Windows-i586-p.exe It's at the right of the red downward
- The download window appears. After some time the download is complete.
Double click the Java icon in the download window. The system will
automatically choose a directory for you for the download, or you may choose
your own. Click OK.
- The install Wizard will appear. By hitting next, you take the
Wizard through the installation steps. At some point, a window appears with
a few options. The top one, Development tools will be selected.
Either hit OK or next.
- Follow the wizard instructions, clicking next and yes when
Finally click finish.
- On your browser get the
www.jcreator.com/download.htm If you are using Windows XP, do the
following: To the right of JCreator Classics you will see JCreator
LE 3.50. Hit the down arrow and select JCreator LE 2.50. Click the
download button. The computer will then ask for your name and email
address. After you have complied, an email message will be sent to your email
address. Click the download link and the Jcreator zip file will be downloaded
by the browser manager.
- If you are using Windows Vista, follow the same procedure. JCreator
on the Vista operating system saves your programs in the same folder as
JCreator is in. This will prevent your program from compiling. Create a new
folder and save your programs there.
- After some time the download is
The WINZIP program will then take over and unzip JCreator.
(If not, using the Windows explorer find and then
click the JCrea250.zip icon.) Click the Wizard button at the upper right
of the Winzip window and click the Next button until the file is
unzipped. Then after closing all applications, start the setup program and
JCreator will be installed.
- After the installation is complete, launch JCreator from the icon
that was placed on the desk top.
- The first window to appear is File associations. Just click next.
- The next window asks for JDK home directory. Browse for the directory and click next.
- The final window asks for JDK JavaDoc directory. If you already downloaded
the JavaDoc file, browse for it and click finish. Otherwise click finish to
continue on without the documentation.
- To compile and run a program, use the "Build" menu. Then, choose
the Execute File option. In version 3.5, this may be the only option
If for some reason, you haven't pointed JCreator to the JDK, do the
- To point JCreator to the JDK folder, start by clicking
Click JDK Profiles. In the JDK Profiles window, the Default
classpath of the selected JDK profile slot must have information in it. If
not, click the JDK version 1.3 , JDK version 1.4 or JDK
version 1.5 profile at the top of the window. The following screen
captures have JDK 1.3 in them. Your's will have JDK 1.5.
Then click Edit, and in the Classes window click
Add and then
Path and select the folder containing the JDK documentation,
and click OK. Then in the Classes window, the JDK directory will
appear at the bottom of the list:
Then click Up
until the selected version appears at the top of the page. The click OK and
finally, OK in the original window.
The reason, in the above, if when you first clicked on JDK Profiles
and all the JDK versions appear in red, is that JCreator is no longer pointing
to actual directories. To correct this, hit the New button and browse
until you find Program file\java then click on the directory that is
labelled the latest version of JDK. Then hit OK twice, and when you
reach the original JDK Profiles window, click the Up button until the
active JDK version is at the top of the window.
