Java 1.6 Installation

Follow the steps to install Java on your computer.

-> Double click the setup file to install jdk into your system.



-> it will install jdk in your system




-> Install it in the default path i.e. c:\program files\java\ , do not change the path.


-> After installing it, set the environment variables as follows

(1) right click My Computer icon
(2) click Properties
(3) A tabbed window appears, click the Advanced tab


-> click the Environment Variables button.
-> here you have 2 sections User Variables and System Variables.

-> Click the New button in the System Variables section and provide the following entries for

Variable Name : classpath

Variable Value :

C:\Program Files\Java\jdk1.6.0\lib\dt.jar;C:\Program Files\Java\jdk1.6.0\lib\tools.jar;.;

-> Click OK after entering the values.

-> C:\Program Files\Java\jdk1.6.0\lib is the default path where java gets installed. It means we have to provide the path where Java is installed, suppose if you have installed java in d:\java, then provide the Variable Value as d:\java\jdk1.6.0\lib\dt.jar;d:\java\jdk1.6.0\lib\tools.jar;.;

where jdk1.6.0 is the folder which is created within the java folder when we install.


-> click the New button again in the System Variables section and provide the following entries

Variable Name : path

Variable Value: C:\Program Files\Java\jdk1.6.0\bin;

-> click OK after entering the values.

-> to check whether Java is installed or not, type the command javac in the command prompt


-> it will list the possible javac options. If it flashes an error saying " 'javac' is not recognized as an internal or external command ..........." than it means that you didnt set the classpath and path variables correctly in the environment variables.
