Hi amit_n_panchal

I have tried the link and I am getting the message

"Old and unsupported versions of Java have also been detected on your system.
Click here for instructions on how to remove them to maintain your system security"

Then I download the installer after the installation as well I am getting the same error. Is there anything that I have missed,

Hi JP2011

I have opened the control panel and then "Add and Remove Programs" There are three softwares installed realted to Java

1. J2SE run time environment 5.0 Update 1
2. Java(TM) 6 update 26
3. Java(TM) 6 update 3


Is that what is reuqired.

It seems that three version of java is installed on your machine.

1. jdk 5u1
2. jdk 6u3
3. jdk 6u26

Can you tell me which version of java you need in your machine?

Hi amit_n_panchal

I am new to Java so I am not aware of the versions. My requirement is I want to practise core Java.

look under the desk?  ;-)

Hi Karan, I hope my last post makes you smile! (my weak sense of humor at its best). You are like me, new to java. If i may speak off topic, id like to recommend these two books. I am about half way through the first book. I think they are very well done.  

hi kiran.
u have 3 versions of java, so remove two of them.
or remove all 3 versions & download one latest version of java.
