Write a program that takes a string as input (e.g., r$EMAIL_ADDRESS#*a&r) and outputs the count of numbers, alphabets, and special characters. For the example input, the output should be: numbers - 2, alphabet - 7, special character - 5.

Question

Accepted Answer

This program counts the number of digits, alphabets, and special characters in a given string.

Use a loop to iterate through each character in the string.
Check if the character is a digit using isdigit() method.
Check if the character is an alphabet using isalpha() method.
Count special characters by checking if the character is neither a digit nor an alphabet.
Example: For input 'r$3y@o9hy#*a&r', output will be: numbers - 2, alphabet - 7, special character - 5.

import java.util.Scanner;

public class Main {

    static void separateCharCount(String input){
        int numCount = 0,alphabetsCount = 0,specialCount = 0;
        for(int i = 0;i='a') || (c<='Z' && c>='A')){
                alphabetsCount++;
            }
            else if(c>='0' && c<='9'){
                numCount++;
            }
            else
                specialCount++;
        }
        System.out.print("numbers - "+numCount +",alphabet - "+ alphabetsCount + ",special character - "+ specialCount);
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String input = scanner.nextLine();
        separateCharCount(input);
    }
