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

Try this method to count digits of an integer number:-

 public int numberOfZeros(int number){
    return ((int) Math.log10(number) + 1);
}

Or you can try this code

      //Declare input as scanner
        Scanner input = new Scanner(System.in);

        //Take input
         System.out.println("Enter Number :");
         no = input.nextInt();
         System.out.println("Enter digit :");
         digit = input.nextInt();

        //add while loop
        while(no>0)
        {
            m=no%10;
            if(m==digit)
                oc++;
            no=no/10;
        }

        System.out.println("Digit occurred "+oc+" times");
