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*/
