Removing spaces between characters using a loop

Question

How can I remove spaces between characters using a loop? I made a program that tests the validity of a social insurance number. However, I'd like to be able to remove the spaces in the input if the users sepeates their SIN using spaces. example (123 456 789 becomes 123456789)
Thank you

Thank you for your response. However, the procudre must be done using a loop.It doesn't have to be done using a loop, as already shown. However if you have some ignorant person telling you you have to have a loop, then here's a solution that uses a loop:String s = "123 456 789";
while (s.contains(" ")) {
  s = s.replaceAll(" ", "");
}
