Example: CheckVowelConsonantIfElse in Java

// CheckVowelConsonantIfElse
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Create a Scanner object to read input from the console
        Scanner scanner = new Scanner(System.in);

        // Step 2: Prompt the user to enter a character
        System.out.print("Enter a character: ");
        char ch = scanner.next().charAt(0); // Read the first character of the input

        // Step 3: Check if the character is an alphabet
        if (!Character.isLetter(ch)) {
            System.out.println(ch + " is not an alphabet.");
        } else {
            // Step 4: Check if the character is a vowel (case-insensitive)
            if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' ||
                ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U') {
                System.out.println(ch + " is a Vowel.");
            } else {
                // Step 5: If it's an alphabet but not a vowel, it's a consonant
                System.out.println(ch + " is a Consonant.");
            }
        }

        // Step 6: Close the scanner
        scanner.close();
    }
