Visual guide to set up classpath in java.

Click "Start" => "My Computer"

Click on the main drive

Go to "Program Files" (Mostly "C:\Program Files") Now Find Java Folder

Open JDK Folder - Where the Compiler is

In the JDK folder right click on any file item and choose "Properties".

From the "Properties Window" click "Location" and Copy the folder path.(In my computer: "C:\Program Files\Java\jdk1.6.0_16\bin")

Now go to Desktop (or Start => My Computer) and Right click on the My Computer and click "Properties".
In "System Properties" click on the "Advanced" tab.
Now Click on the "Environment Variables".
In the Environment Variable window click "New" to create a new variable
Now in the Variable Name field type "Path" without " mark.
And Variable value is where the compiler is(we copied it...remember..)... Paste it here(Mine is C:\Program Files\Java\jdk1.6.0_16\bin)
Now click ok.

To test:
Go to command line(Start Menu => Run => type "cmd" without " marks.

Now type "javac" without " marks.
If you see something like this.... Usage: javac .....
You correctly did it....
