A CMS is not exclusive to PHP, there are no language constructs which are exclusive to PHP which mean that it is the only language that you can write a CMS in.
JAVA provides database connectivity.
JAVA and PHP are cross platform.
Now you really are showing how little you know, and how a little knowledge is dangerous, please do not promote this idea any more.Any program that is written using Java is virus free.
More incorrect rubbish.Because of its adaptability to changing the environment, java prevents memory wastage and enhances the performance of any application.
Because of its robust memory management system, the errors are eliminated during compiling and runtime.
You really have no right peddling this, all that you have done is show that you do not know what you are talking about. I presume that this has been cut and edited from various articles which also didn't know what they were talking about or have been taken out of context and badly pieced together.
It's difficult enough learning program development without such rubbish confusing the situation, please stop.
