✅ Java Program: Count Vowels and Numbers

import java.util.Scanner;

public class VowelAndNumberCounter {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

// Take input from the user

System.out.print(“Enter a string: “);

String input = scanner.nextLine();

// Initialize counters

int vowelCount = 0;

int numberCount = 0;

// Convert input to lowercase to simplify vowel check

input = input.toLowerCase();

// Loop through each character

for (int i = 0; i < input.length(); i++) {

char ch = input.charAt(i);

// Check if the character is a vowel

if (ch == ‘a’ || ch == ‘e’ || ch == ‘i’ || ch == ‘o’ || ch == ‘u’) {

vowelCount++;

}

// Check if the character is a digit

if (Character.isDigit(ch)) {

numberCount++;

}

}

// Output the results

System.out.println(“Number of vowels = ” + vowelCount);

System.out.println(“Number of numbers = ” + numberCount);

}

}
