Counting Digits in a Given Number

Counting Digits in a Given Number

A typical mechanism of converting to a string, traversing and counting has a lot of processing to complete.

Instead, the code below shows a combination of methods in Math package to help us achieve the same.

*/public class DigitCount{   public static void main(String args[])   {      DigitCount digitCount = new DigitCount();      digitCount.proceed();   }      private void proceed()   {      int aNumber = 56554;      System.out.println("Digit count in " + aNumber + ": " + Math.round(Math.floor(Math.log10(aNumber)) + 1));   }}/*

Expected output:

[root@mypc]# java DigitCountDigit count in 56554: 5*/
