Java Program to check vowel or consonant using switch case

In the following question, we are supposed to ask the user for character input and check if the input is a vowel or not using Switch Case construct.

Algorithm:

1. Accept and store user input.
2. Make a copy of the input and store it.
3. Convert the copy to uppercase for easier comparison and uniformity.
4. Use a switch-case construct to check for vowels.
5. Print the result based on the vowel check.

/* Program to check if entered character is vowel or not using Switch Case */

import java.util.Scanner;

class SwitchVowel {
    public static void main() {
        Scanner inp = new Scanner(System.in);
        System.out.print("\nEnter Character: ");
        char c = (inp.nextLine()).charAt(0);
        char z = Character.toUpperCase(c); // Changing Value to UpperCase for uniformity.

        switch (z) { // Checking Vowel Character using Switch Case
            case 'A':
            case 'E':
            case 'I':
            case 'O':
            case 'U':
                System.out.println(c + " is a Vowel.");
                break;

            default:
                System.out.println(c + " is a Non-Vowel Character.");
        }
    }
}

Output:

Enter Character: X
X is a Non-Vowel Character.

 Enter Character: u
u is a Vowel.

 Enter Character: 5
5 is a Non-Vowel Character.
