I actually have no idea why it's required, other than to say that it is a syntactical convention. In the same way that a function is (defined function-name()) in Lisp/Scheme, or there are do..end blocks in Ruby, the syntax of a Java Main function is with String[] args.

As for not using command line arguments, it's entirely dependent on the program. Entirely. I write programs in java all the time that take command line arguments; it's just a question of what you're trying to accomplish.
