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

4 Réponsescan someone tell me how to make it impossible for a user to type a 'userchoice1[x]' value that does not range from 1 - 10.
If you also know a way I can make the user input another value for the 'userchoice1[x]' variable if it is less than 1, I'll appreciate you share the knowledge with me.
please see the short code below
