I copied this code from one of the posts:

public static void main(String... args){
Test t=new Test();
t.start();
t=null; // at this line d will be GCed.
}

Is it legal to have main() signature as above? Explanations are welcome

Yes Infact I have posted this code

If you use String... args, here args is nothing but a one dimensional String array.

So it works there as well but REMEMBER only on j2sdk 1.5

You can test this class.

Compile it on 1.5



You will get compilation error... at line 3, meth(java.lang.String...) is already defined in Test

yes it was ur code.....
does it mean that....

String...args
int...x

are arrays of String and int respectively with args and x referring to it and args[0] and x[0] are legal calls
