        char character = 'a';

        if (character == 'a' || character == 'e' || character == 'i' || character == 'o' || character == 'u') {
            System.out.println(character + " is vowel");
        } else {
            System.out.println(character + " is consonant");
        }
    }
}
Output:
a is vowel

                } else {
                    System.out.println("Input is not an alphabet");
                }
            }
        }
    }
}
Output:
Enter a character : 
J
J is a Consonant
