Define a class to accept a String and print the number of digits, alphabets and special characters in the string.

Example:
S = "KAPILDEV@83"
Output:
Number of digits – 2
Number of Alphabets – 8
Number of Special characters – 1

Given Input:

KAPILDEV@83

Expected Output:

No. of Digits = 2
No. of Alphabets = 8
No. of Special Characters = 1

Program:

import java.util.Scanner;

public class RansariCount {

    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);  // Create Scanner object for input
        System.out.println("Enter a string:");
        String str = in.nextLine();  // Take user input for the string

        int len = str.length();  // Get the length of the input string

        int ac = 0;  // Counter for Alphabets
        int sc = 0;  // Counter for Special characters
        int dc = 0;  // Counter for Digits
        char ch;     // Variable to store each character

        // Loop through each character in the string
        for (int i = 0; i < len; i++) {
            ch = str.charAt(i);  // Get the character at index i

            // Check if the character is a letter
            if (Character.isLetter(ch))  
                ac++;  // Increment the alphabet counter

            // Check if the character is a digit
            else if (Character.isDigit(ch))  
                dc++;  // Increment the digit counter

            // Check if it's a special character (not a letter or digit)
            else if (!Character.isWhitespace(ch))  
                sc++;  // Increment the special character counter
        }

        // Print the results
        System.out.println("No. of Digits = " + dc);
        System.out.println("No. of Alphabets = " + ac);
        System.out.println("No. of Special Characters = " + sc);
        
        in.close();  // Close the Scanner object
    }
}

Output:

No. of Digits = 2
No. of Alphabets = 8
No. of Special Characters = 1
