guys what does this java code mean?

[buklu]

System.out.print("Integer in reverse order=");
        while (n!=0) {
        int digit = n%10;
        System.out.print(digit);
        n=n / 10;
        }
        System.out.println();

while n is not equal to 0 do integer digit n remainder 10 then print that digit and n equal n divided by 10  then print blank line as spacer. looks a loop for getting all the tens places printed out

[Turretgaming]

hope that helps you

what is n remainder 10?

say you have number 362

 

362 % 10 = 2 (int) 2 = 2

print 2

362 / 10 = 36.2

 

36.2 % 10 = 6.2  (int) 6.2 = 6

print 6

36.2 / 10 = 3.62

 

3.62 % 10 = 3.62  (int) 3.62 = 3

print 3

3.62 / 10 = 0.362

 

now presumably you would want it to stop here but n != 0 so it will keep adding 0 so the while loop should read while(n > 0)

i agree. this way it wont loop for ever. what computer science class is this for btw i assume its for a class as in my freshman year we made this loop too.

thanks bro

changing it to n > 0 makes no difference. 0.362 is greater then 0. So the loop will continue anyway. dividing by 10 forever. This loop will never end. i'd make it n > 1, so it will actually stop.
