Find Whether Given Character is Vowel or Consonant in Java

In this article, we will learn to find whether a given character is a vowel or consonant using Java. In the English alphabet, the characters 'a', 'e', 'i', 'o', and 'u' are vowels and the remaining letters are consonants. To find whether the given letter is a vowel or consonant.

Using a loop and or operator verify whether the given character is 'a' or 'e' or 'i' or 'o' or 'u' else it is consonant.

Steps to find whether given character is vowel or consonant

Following are the steps to find whether given character is a vowel or consonant?

• First we will import the Scanner class from java.util package.
• After that prompt the user to enter a character and store it in ch.
• Use an if statement to check if ch is 'a', 'e', 'i', 'o', or 'u'. If true it's a vowel, otherwise, it's a consonant.
• Print whether the character is a vowel or consonant.
  

Java program to find whether the given character is a vowel or consonant

Below is the Java program to find whether the given character is a vowel or consonant ?

import java.util.Scanner;
public class VowelOrConsonant {
   public static void main(String args[]){
      System.out.println("Enter a character :");
      Scanner sc = new Scanner(System.in);
      char ch = sc.next().charAt(0);
      if(ch == 'a'|| ch == 'e'|| ch == 'i' ||ch == 'o' ||ch == 'u'||ch == ' '){
         System.out.println("Given character is an vowel");
      }else{
         System.out.println("Given character is a consonant");
      }
   }
}

Output

Enter a character :
a
Given character is an vowel
Enter a character :
l
Given character is a consonant

Code Explanation

The program begins by reading a character from the user using the Scanner class. It then checks if the character is one of the vowels ('a', 'e', 'i', 'o', 'u') through an if statement. If the character matches any of these vowels, the program outputs "Given character is a vowel." If it doesn't match, the program concludes that the character is a consonant and prints "Given character is a consonant."
