check whether an Alphabet is Vowel or Consonant
Table of Contents
In this article, we will discuss the concept of Java program to check whether an Alphabet is Vowel or Consonant
In this post, we are going to learn how to write a program to check whether given English alphabet is Vowel or consonant using various ways in Java language
In this code, we are going to learn how to check the given English alphabet is Vowel or consonant using if-else in Java language
Program 1
import java.util.Scanner;
class Check_Alpha_Vowel1{//class declaration
public static void main(String args[]){
char ch;//Declare a local character variable
Scanner scan=new Scanner(System.in);
//Ask input from the user
System.out.print("Enter an Alphabet: ");
//get input and store ch variable
ch=scan.next().charAt(0);
if(ch=='a'||ch=='A'||ch=='e'||ch=='E'||ch=='i'||ch=='I'||ch=='o'||ch=='O'||ch=='u'||ch=='U')
{//check the given Alphabet is vowel or consonant
System.out.print(ch+" is a vowel");
}
else{
System.out.print(ch+" is a consonant");
}
}
} When the above code is executed, it produces the following result
Case 1
Enter an Alphabet: E E is a Vowel
Case 2
Enter an Alphabet: r r is a Consonant
In this code, we are going to learn how to check the given English alphabet is Vowel or consonant using if-else-if else in Java language
Program 2
import java.util.Scanner;
class Check_Alpha_Vowel2{//class declaration
public static void main(String args[]){
char ch;//Declare character (local) variable
Scanner scan=new Scanner(System.in);
//This statements takes input from the user
System.out.print("Enter a character:(Alphabet or Not) ");
//get input and it is stored ch variable
ch=scan.next().charAt(0);
if(ch=='a'||ch=='A'||ch=='e'||ch=='E'||ch=='i'||ch=='I'||ch=='o'||ch=='O'||ch=='u'||ch=='U')
{//this statements checks vowels
System.out.print(ch+" is a vowel");
}
else if//"else if" statement checks consonant
((ch>='A' && ch<='Z')||(ch>='a' && ch<='z')){
System.out.print(ch+" is a consonant");
}
else{
System.out.print(ch+" is not an Alphabet");
}//print non-alphabet characters
}
} When the above code is executed, it produces the following result
Case 1
Enter a character:(Alphabet or Not) U U is a Vowel
Case 2
Enter a character:(Alphabet or Not) t t is a Consonant
Case 3
Enter a character:(Alphabet or Not) 5 5 is not an Alphabet
In this code, we are going to learn how to check the given English alphabet is Vowel or consonant using Nested if in Java language
Program 3
import java.util.Scanner;
class Check_Alpha_Vowel3{//class declaration
public static void main(String args[]){
char ch;//local variable
Scanner scan=new Scanner(System.in);
//This statements takes input from the user
System.out.print("Enter a character: ");
//get input and it is stored ch variable
ch=scan.next().charAt(0);
if
((ch>='A' && ch<='Z')||(ch>='a' && ch<='z')){ //outer if use to check consonant
if(ch=='a'||ch=='A'||ch=='e'||ch=='E'||ch=='i'||ch=='I'||ch=='o'||ch=='O'||ch=='u'||ch=='U')
{//inner if statements checks vowels
System.out.print(ch+" is a vowel");
}
else{//display consonant
System.out.print(ch+" is a consonant");
}
}
else{
System.out.print(ch+" is not an Alphabet");
}
}
} When the above code is executed, it produces the following result
Case 1
Enter a Alphabet: F F is a Consonant
Case 2
Enter a Alphabet: I I is a Vowel
Case 3
Enter a Alphabet: & & is not an Alphabet
In this code, we are going to learn how to check the given English alphabet is Vowel or consonant using Switch case statements in Java language
Program 4
import java.util.Scanner;
public class CheckVowConsSwitchcase1{
public static void main(String args[]){
char ch;//variable declaration
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.println("Enter the Alphabet for check vowel or consonant ");
ch=scan.next().charAt(0);;// store the input in ch variable from the user
switch(ch){
//check lower case vowel letters
case 'a':
System.out.println(ch+" is an vowel");
break;
case 'e':
System.out.println(ch+" is an vowel");
break;
case 'i':
System.out.println(ch+" is an vowel");
break;
case 'o':
System.out.println(ch+" is an vowel");
break;
case 'u':
System.out.println(ch+" is an vowel");
break;
//check upper case vowel letters
case 'A':
System.out.println(ch+" is an vowel");
break;
case 'E':
System.out.println(ch+" is an vowel");
break;
case 'I':
System.out.println(ch+" is an vowel");
break;
case 'O':
System.out.println(ch+" is an vowel");
break;
case 'U':
System.out.println(ch+" is a vowel");
break;
default:
System.out.println(ch+" is a consonant");
break;
}
}
}
When the above code is executed, it produces the following result
Case 1
Enter the Alphabet for check vowel or consonant E E is a vowel
Case 2
Enter the Alphabet for check vowel or consonant g g is a consonant
