Now inside the loop each time we have to find the last digit of user given number and then calculate the power of that number with total no of digits in the “num”, round off the result and store it in one temporary variable “sum” once the loop is finished we have to check if the value of variable sum is equivalent to user given number, if yes, then it is an Armstrong number. But, maybe I am wrong and that's why I am here. Below is the example. There is a method called isdigit() in String class that returns true if all characters in the string are digits and there is at least one character, false otherwise. [\W] matches (not (alphanumeric or underscore)), which is equivalent to (not alphanumeric and not underscore) You need [\W_] to remove ALL non-alphanumerics.
