Java / JCreator - Installation and Running Instructions

Skip to the JCreator 4.5 running instructions...

Note: at the time of writing the latest version of Java is Java SE 7 JDK

from oracle.com. This document refers to the installation of a previous version:

Java(TM) SE Development Kit 6 Update 26 from java.sun.com.

The installation method is similar for different versions.

In order to write, run and understand Java programs,

you need a good textbook, the (free) Java development kit (JDK)

with documentation, and a good Java development environment

such as freeware JCreator.

Java/Documentation, JCreator installation and usage

are explained in detail below...

Complete all 4 steps in order:

Step 1: Install Java

Step 2: Install Java Documentation

Step 3: Install JCreator LE ver 4.50 or 3.50

Step 4: Run JCreator LE ver 4.5 (Step 4: Run JCreator LE ver 3.5)

Step 1: Install Java

Before you can type in and run a Java program

you must first download and install the Java Development Kit

onto your computer...

Go to:

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

NOTE: You will be redirected from the old page below,

to the new download page at Oracle.com.

The java download page has moved from java.sun.com

to oracle.com...

On the Java SE Downloads page, scroll down to see:

JDK 6 Update 7

Further down on the same page you will see:

Java SE 6 Documentation

You need to download both of these files

JDK 6 Update 7 Download (Click this button)

PLEASE NOTE THAT THE FOLLOWING SCREENS SHOW JDK 6 Update 2,

- THE FILE NAMES WILL BE SLIGHTLY DIFFERENT FOR LATER UPDATES...

Scroll down ...

In the Required: section, click in the circle

to Accept License Agreement

then, if you're using a Windows operating system,

click in the box to select the first file in the list,

then click on the orange download button

to download the file to your computer.

Click on the Save File t button to download the file...

Click to Open the file.

IMPORTANT:

Make a note of the folder where Java is installed.

If you didn't specify anything different in the Java installation,

the default path is:

C:\Program Files\Java\jdk1.6.0_02\

for the following:

"In Windows, you have to modify your command search path before you'll be able to run things properly. [One might think the installer would do this. One would be wrong.] Right-click the “My Computer” icon and select Properties → Advanced → Environment Variables. From “System variables”, edit “Path”. To the start of its value, add: (notice the semicolon between that and the next entry)

C:\Program Files\Java\jdk1.5.0_03\bin;

(You may have to adjust slightly for the version of the JDK that you have.)"

If you're running Windows XP and you followed these installation instructions to the letter, then the default path is:

C:\Program Files\Java\jdk1.6.0_02\

and you should set the environment variable search path to:

C:\Program Files\Java\jdk1.6.0_02\bin;

Java Documentation

Java comes with extensive documentation,

which is an essential tool for programmers.

It has to be downloaded separately,

but once downloaded, it will automatically

link to your development environment

so that you can quickly and easily get online help

on the Java language.

And for more experienced programmers

there are also very detailed reference documents here.

Step 2: Install the Java Documentation

Go to:

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

On the Java SE Downloads page, scroll down to see:

Java SE 6 Documentation Download

Click on the Download button.

In the Required: section, click in the circle

to Accept License Agreement

then, if you're using English documentation,

click the first file in the list,

to download the file to your computer.

Click to Open the file.

IMPORTANT:

Extract the docs folder from the zip file,

to the Java installation folder,

which by default is:

C:\Program Files\Java\jdk1.6.0_02\

It will take a few minutes to extract the documents to the docs folder.

Contents of the Java folder:

C:\Program Files\Java\jdk1.6.0_02\

Contents of the Java folder with docs:

C:\Program Files\Java\jdk1.6.0_02\

Note: there are approximately 12,000 document pages occupying approx 260 MB:

Step 3 - Installing JCreator LE version 4.50 ( or version 3.50)

Once Java and its documentation

is installed on your computer,

you then download and install the free

Java development environment Jcreator,

so that you can type in, compile

and run your Java programs.

When JCreator first runs,

it will automatically detect your Java JDK folder,

and you can set the documentation path (see above).

Click the following link to

download and install Jcreator.

Click to download the freeware version of JCreator.

Follow the friendly instructions.

For the latest Light Edition version,

click on the second DOWNLOAD button in the screen below...

The remaining instructions are for JCreator LE v4.50,

but can equally be used for JCreator LE v3.50...

Click on the second DOWNLOAD button in the screen above...

Click on the OK t button...

Click on Open

Double click on Setup.exe

Click on the Next > t button...

Click in the circle to accept the agreement.

Click on the Next > t button...

Click on the Next > t button...

Click on the Yes t button...

Click on the Next > t button...

Click on the Next > t button...

Click on the Install t button...

Click on the Finish t button...

Click on the Next > t button...

Click on the Next > t button...

If you installed Java and the Java Documentation

as described in Step 1 above, JCreator will automatically

find the path to the installed Java compiler and its documentation.

Click on the Finish t button...

to complete the JCreator installation,

and launch JCreator....

Step 4 - Running Java programs on JCreator 4.5

Launch JCreator...

Click on the Close t button to continue...

The window below shows the Start Page for JCreator...

The window above shows the Start Page for JCreator.

The Start Page includes instructions for installation and operation

of the JCreator program. You can refer to the Start Page at any time.

To test that JCreator and Java are set up correctly,

follow these simple instructions:

Use a folder called C:\temp to save your files.

Save this file as FirstProgram.java in C:\temp

Save this file as SavitchIn.java in C:\temp

Start JCreator

If you see the Tip of the Day window, close it.

Click on File -> Open

to open both files in C:\temp

You should then see the following screen:

Click on the tab for FirstProgram.java to make it the active file,

then click on Build -> Build File

You will see the following message in the Build Output window if the Java source code compiled to object code successfully.

--------------------Configuration: <Default>--------------------

Process completed.

Click on the tab for SavitchIn.java to make it the active file,

then click on Build -> Build File

You will see the following message in the Build Output window if the Java source code compiled to (executable) object code successfully.

--------------------Configuration: <Default>--------------------

Process completed.

If you do not see the message above when you compile a .java file,

this means that you have an error somewhere in your program.

Read the error message, go back to your source code and find

and correct (debug) the error/s.

Use Build -> Build File repeatedly until you get the message:

--------------------Configuration: <Default>--------------------

Process completed.

Once you see the message above for both program files:

FirstProgram.java and SavitchIn.java, proceed as follows:

To run the example program:

Click on the FirstProgram.java tab to ensure that this is the active file.

Click on Run -> Run File

--------------------Configuration: <Default>--------------------

Hello out there.

Want to talk some more?

Answer y for yes and n for no.

If you see the General Output window above,

with the same text, you have successfully loaded

both Java and JCreator,

and both are running correctly.

If you need more help using JCreator,

when running JCreator click key F1,

Getting Help
