Java can run directly on any platform without manual intervention because it is written in pre-compiled portable byte code whereby interpreters or runtime packages are standard elements of all computer platforms.

The scripts then become exploits and hence cause trouble or damages to the system. There are attempts to make the scripting languages in the web secure but at the same time there are individuals who are notorious individuals ...
