Reverse number in java very simple logic for beginners.

in this video, I explain how to reverse number with simple logic for beginners;

public class ReverseNumber {

public static void main(String[] args) {

int num = 1234, reversed = 0;

while(num != 0) {
int digit = num % 10;
reversed = reversed * 10 + digit;
num /= 10;
}

}
}
