How to add a new method called numberOfDigits() in java?

Question

I have a program called public class ZeroCounter {. I want to add a new method to it called numberOfDigits() and add a line to test it in the main() method. How should I go abo

Answer 1

public class ZeroCounter   {
  public static void main(String[] args) {
         System.out.println("Enter a nonnegative number:");
         Scanner keyboard = new Scanner(System.in);
         int number = keyboard.nextInt( ) ;

         System.out.println(number + " contains " + numberOfZeros(number) + " zeros.");
  } // End of main

  private static int numberOfZeros(int number) {
         int result = ///// calculation
         return result;
  }
}

You might want to read up a bit more on Java and how classes, methods and functions work first before going any further however.
