Count Digits in a String
Go through each character and count how many are digits (0-9).
Example
String text = "W3Schools was founded in 1998";int count = 0;for (char c : text.toCharArray()) { if (Character.isDigit(c)) { count++; }}System.out.println("Digits: " + count);Explanation: We loop through each character of the string. The methodCharacter.isDigit() checks if the character is a digit. For the example above, the program finds 5 digits.
