Java program to find whether given Alphabet is vowel or consonant using switch case

Java program to find whether given Alphabet is vowel or consonant using switch case

In this article, we will discuss the concept of Java program to find whether given Alphabet is vowel or consonant using switch case

In this post, we are going to learn how to write a program to  check whether given English alphabet is Vowel or consonant  using switch  case in Java language

Code to check given Alphabet is Vowel or consonant

Code to check given Alphabet Vowel or consonant, using switch   – #1

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 1

import java.util.Scanner;
public class CheckVowConsSwitch_case{
public static void main(String args[]){
  char ch;//character 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  ");
//Ask input from the user
ch=scan.next().charAt(0);;// store the input in ch variable

switch(ch){
  //check lower case vowel letters
  case 'a':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'e':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'i':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'o':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'u':
  System.out.println(ch+" is a vowel");
  break;
  
  //check upper case vowel letters
  case 'A':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'E':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'I':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'O':
  System.out.println(ch+" is a vowel");
  break;
  
  case 'U':
  System.out.println(ch+" is a vowel");
  break;
  
  default://print if the character is constant
  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
S
S is a consonant

Case 2

Enter the Alphabet for check vowel or consonant
u
u is a Vowel

 

Code to check given Alphabet Vowel or consonant, using switch- #2

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 2

import java.util.Scanner;
public class CheckVowelConsSwitchcase1{
public static void main(String args[]){
  char ch;//variable declaration
  boolean isVowel=false;//Declare a boolean variable

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter the character for check vowel or consonant ");
ch=scan.next().charAt(0);;// store the input from the user

switch(ch){
  //check lower case vowel letters
  case 'a':
  case 'e':
  case 'i':
  case 'o':
  case 'u':
  
  case 'A':
  case 'E':
  case 'I':
  case 'O':
  case 'U':
  isVowel=true;
}
  
  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 a Alphabets");
  }
}
  
}
  
}

When the above code is executed, it produces the following result

Case 1

Enter the character for check vowel or consonant
F
F is a consonant

Case 2

Enter the character for check vowel or consonant
o
o is a Vowel
