Example: CheckVowelConsonantSwitch in Java

// CheckVowelConsonantSwitch
import java.util.Scanner;

// Main class containing the entry point of the program

        // Step 1: Create a Scanner object to read input
        Scanner scanner = new Scanner(System.in);

        // Step 2: Prompt for character input
        System.out.print("Enter a character: ");
        char ch = scanner.next().charAt(0);

        // Step 3: Check if it's an alphabet
        if (!Character.isLetter(ch)) {
            System.out.println(ch + " is not an alphabet.");
            scanner.close();
            return; // Exit if not an alphabet
        }

        String result = "";
        // Step 4: Use a switch statement to check for vowels
        switch (Character.toLowerCase(ch)) { // Convert to lowercase for simpler cases
            case 'a':
            case 'e':
            case 'i':
            case 'o':
            case 'u':
                result = "Vowel";

            default:
                result = "Consonant";
        }

        // Step 5: Print the result
        System.out.println(ch + " is a " + result + ".");

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