Write a program to check whether an alphabet is vowel or consonant.

To understand this program, you should have knowledge of basic if-else statement. There are 6 Vowels in alphabets namely ‘a’, ‘e’, ‘i’, ‘o’, ‘u’. And other 21 Alphabets are consonant. So, if the entered character is any of 6 defined above, we will print vowel else consonant.

public class VowelOrConsonant {

    public static void main(String[] args) {

        char ch = 'o';

        if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' )
            System.out.println(ch + " is a vowel");
        else
            System.out.println(ch + " is a consonant");

    }
}

Output

o is a vowel

As you know, any java program starts from main method. here, we have assigned alphabet ‘o’ to a char variable ch.

The if statement checks entered char is == a. if not, it checks the next condition and likewise. Double pipe operator || is OR symbol.

If it finds a match in if statement, it prints vowel else it prints consonant.

Additionally, if you assign any Capital letter to char variable, it will print consonant which should not happen.

Assignment: Write a program to include Capital vowels in the program as well.
