Set PATH to JDK on Windows 8 (official version)

Last post described how to "Download and Install JDK 7 on Windows 8 (Official version)".

After downloaded and install JDK 7 on Windows 8, now open a Command Prompt window to run java or javac...!!!

you can optionally set PATH environment variable to JDK so that you can conveniently run the JDK executable files (javac.exe, java.exe, javadoc.exe, and so forth) from any directory without having to type the full path of the command.

To set path, search "Environment Variables" in "Settings", click "Edit the system environment variables".

Click "Environment Variables".

Select System variables of Path, and click Edit...

Add the location of the bin folder of the JDK installation, in my case it is "D:\Program Files\Java\jdk1.7.0_11\bin".

Now, you can close and re-open Command Prompt window, type java and javac to varify your setting.

Install JDK 7 on Windows 8 (Official version)

Note: You must have administrative permissions in order to install the JDK on Microsoft Windows.
Note: Installers for JDK 7u6 and later install the JavaFX SDK and integrate it into the JDK installation directory.

Visit http://www.oracle.com/technetwork/java/javase/downloads/index.html, click the download Java Platform button.

Scroll down to check Accept License Agreement, select Java SE Development Kit 7u11, jdk-7u11-windows-i586.exe for Windows x86.

Run the downloaded installer.

Select optional features and location to install.

Select location to install jre.

Install JDK 7 and update-alternatives on Ubuntu 12.10

Download update JDK here: http://www.oracle.com/technetwork/java/javase/downloads/index.html, click the DOWNLOAD Java Platform graph.

Scroll download to check the box of Accept License Agreement, and select the package to download. In this case, jdk-7u11-linux-i586.tar.gz for Linux x86 is selected.

Move the downloaded .tar.gz archive binary to the directory you want to install.

Open a Terminal, the the command to unpack the tarball and install the JDK:
$tar zxvf jdk-7u11-linux-i586.tar.gz

For example, if you download the .tar.gz is /home/you, your installed directory will be /home/you/jdk1.7.0_11.

Then, you have to update alternatives for javac and java:
$sudo update-alternatives --install /usr/bin/javac javac /home/you/jdk1.7.0_11/bin/javac 1
$sudo update-alternatives --install /usr/bin/java java /home/you/jdk1.7.0_11/bin/java 1

If you have more than one javac installed, you have to config your javac alternative
$sudo update-alternatives --config javac
$sudo update-alternatives --config java

Finally, delete the downloaded .tar.gz after then.
