Starting a Java program with no arguments (as discussed in the thread before) results in new String for args, hence args is a valid Array, the loop does have nothing to iterate over, and also has no reason to throw Exceptions.

is it similar to assigning value to variable s i,e s=args;
if so where is size declaration for args... this seems to be silly but just wanted to understand the syntax: for (String s:args)
I'm not quite sure what you're having trouble with. The construct is called a "for-each" loop, and was introduced in version 5 for doing precisely what you see without the need for indexes.
As to size declarations: why would you need one? The array (args) already has a size.
Perhaps you could elaborate on exactly what it is you don't understand.
Isn't it funny how there's always time and money enough to do it WRONG?
