Remove the comma after the last number in a loop [duplicate]

Question

this is my code

 System.out.println("Enter any integer number ");
int number = scan.nextInt();
while (number > 0) { System.out.print( number % 10 + ",");number = number / 10;}

To clarify if the user enter 1234 the output should be 4,3,2,1,

how can i edit the code to remove the comma after the last num? something like 4,3,2,1

Since everyone is having a field day, here's mine:

while (number > 0) {
    System.out.print( number % 10 + ((number/=10)>0 ? "," : ""));
}
