Question

write a java program to enter a letter and check if is a vowel or consonent

Answer 1

Check whether an alphabet is vowel or consonant using if..else statement

public class VowelConsonant { public static void main(String[] args) { char ch = 'i'; if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' ) System.out.println(ch + " is vowel"); else System.out.println(ch + " is consonant"); } }

When you run the program, the output will be:

i is vowel

In the above program, 'i' is stored in a char variable ch. In Java, you use double quotes (" ") for strings and single quotes (' ') for characters.

Now, to check whether ch is vowel or not, we check if ch is any of: ('a', 'e', 'i', 'o', 'u'). This is done using a simple if..else statement.

We can also check for vowel or consonant using a switch statement in Java.
