JDK environment

Description:: Sun Microsystems provides the most typical Java tools, the standard compiler "javac", the Java Virtual Machine, the standard Java API documentation and much more.
Download at:: http://java.sun.com/j2se/1.5.0/download.jsp - pick " JDK 5.0 Update 7", Windows Offline installation (do NOT pick JRE, as it is not for developers) and "J2SE 5.0 Documentation". Pick newer versions, if they are available.
Preconditions:: none

Open file %CD%/java/jdk-1_5_0_07-windows-i586-p.exe * Agree to the default directory and other default options. * Create a new System variable JAVA_HOME, which points to the directory where JDK is installed - in our case it is c:\Program Files\Java\jdk1.5.0_07 (see section Environment Variables on how to create such variables).
Edit the System variable Path by replacing its previous value, which looks like this
```
some_directory1;some_directory2;...
```
with the following one
```
%JAVA_HOME%\bin;some_directory1;some_directory2;...
```
The order of the directories written to Path is usually irrelevant (so it would be possible to add stuff to the very end of the variable), but it is recommended to add the entry %JAVA_HOME%\bin to its very beginning, since then the possible errors or other Java versions later in the Path variable do not affect running of JDK 1.5. (see se section Environment Variables on how to edit System variables such as Path).

Close any Total Commander or DOS windows, if they are open. Start a new Total Commander application.
Open a new DOS window in any one of the directories currently selected by the Total Commander by selecting a menu item Commands->Run DOS

In the DOS window type "java -version" and check the response:

c:\temp>java -version
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition ...

Unzip the file %CD%\java\jdk-1_5_0-doc.zip (namely the directory docs contained in the ZIP file) to the %JAVA_HOME% directory. This should create a subdirectory c:\Program Files\Java\jdk1.5.0_07\docs with many HTML files.
Open the index.html file found at the top level in the docs directory. Select the link "API & Language" and then under that title the link "Java 2 Platform API Specification".
A browser window with 3 frames appears. Add this page it to your Internet Explorer favorites (or Firefox Bookmarks).

In the upper-left frame find the package "java.lang" and click it. Then in the bottom-left frame find the class "String" or "Object". Click that link. A documentation page for the given class should appear in the right side frame.

Run the file %CD%\java\j2sdk-1_4_2_11-windows-i586-p.exe
Pick C:\Program Files\Java\j2sdk1.4.2_11 as the installation folder (instead of the suggested C:\j2sdk1.4.2_11).
Uncheck the Browser Plugin options, press [Install], wait until JDK and JRE is installed and press [Finish]. If prompted, agree to restart the computer.
Do NOT redefine JAVA_HOME variable.
JDK 1.4 is needed, if you wish to do Java MIDlet development with Java (see section Sun Java Wireless Toolkit).
