Can someone explain this code to me....
class ReverseNumberDemo
{ public static void main(String args[]) {
int num=123456789;
int reversenum =0;
while( num != 0 ) {
reversenum = reversenum * 10;
reversenum = reversenum + num%10;
num = num/10; }
System.out.println("Reverse of specified number is: "+reversenum);
}
}
the thing I don't get is the reversenum part......isn't reversenum=0 so wouldn't reversenum*10=0

public static void main (string[ ] args)
i have understood little bit that public means for whole method.
static?
void?
main is a method which creates a string array named args. why the name args?
please explain and correct if i am wrong?

I made a WindowBuilder class on Eclipse, but when I try run that class, it say that I need to put a "public static void main(String[] args){}", ok, I put it into the class, and some elements are incompatibles with the "public static void..."
