10. Write a Java method to count the number of digits in an integer with the value
(the integer may be assumed to be non-negative.)
💡Code:
public class DigitCounter { public static int countTwos(int number) { String numberStr = String.valueOf(number); int count = 0; for (int i = 0; i < numberStr.length(); i++) { if (numberStr.charAt(i) == '2') { count++; } } return count; } public static void main(String[] args) { int number = 22253; int numberOfTwos = countTwos(number); System.out.println("The number of 2s in " + number + " is: " + numberOfTwos); } }
