Example: reverse a number using arithmetic operations

//continue to loop until  a value is equal to 0

public class ReverseNum{
  
  public static void main(String[] args {
  
  int a = 543;
  int reverse = 0;
  
 while(a!=0){ //itera the process
 
 int digit = a%10; //isolate the last digit number
 
 reverse = digit + (reverse*10); //append last digit to reverse
 a=a/10; // remove the last digit from number
   } 
   System.out.println(reverse);
   
     } }
