In this java program, you’ll learn how to check whether an alphabet is a vowel or consonant Java. And we are doing this by using if...else and switch statements in java. The alphabets A, E, I, O, and U (lowercase and uppercase) are known as Vowels, and the rest of the alphabets are known as consonants.
Here are the programs to check whether an alphabet is a vowel or a consonant.
/* Java Program to Check Whether an Alphabet is Vowel or Consonant Using if..else statement */
import java.util.Scanner;
public class JavaPrograms {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter a character : ");
char ch = scanner.next().charAt(0);
// closing scanner class(not mandatory but good practice)
scanner.close();
if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'A' || ch == 'E' || ch == 'I'
|| ch == 'O' || ch == 'U') {
System.out.println(ch + " is vowel");
} else if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) {
System.out.println(ch + " is consonant");
} else {
System.out.println(ch + " is not an alphabet");
}
}
}
Enter a character :
t
t is consonant
Enter a character :
5
5 is not an alphabet
Enter a character :
I
I is vowel

switch (ch) {

}
if (isVowel == true) {
System.out.println(ch + " is a Vowel");
} else {
if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z'))
System.out.println(ch + " is a Consonant");
else
System.out.println(ch + " is not an alphabet");
}
}
}
Enter a character :
t
t is a Consonant
Enter a character :
a
a is a Vowel
Enter a character :
222
2 is not an alphabet
