Q:

java script can not automatically write to hard disk But Java can do so

I was just reading one of the JavaScript resource and found following statement written.

javascript can not automatically write to hard disk But Java can do so.

Can somebody please elaborate?

A:

Javascript is a scripting language that lives inside the browser. As such it is bound and restricted by the browser.
Java on the other hand is being executed as a stand alone application. Having all the rights of the person currently logged in. This means that if the logged in user has rights to write to the hard drive so does the java program.
Luckily javascript does not get those rights from the browser. The major reason for this is security. You do not want a virus written to your hard drive while just browsing a website.
And indeed Javascript is by no means Java, it is not even close to it.
