Java program to count vowels and consonants in a string

Java program to count vowels and consonants in a string

In this article, we will discuss the concept of Java program to count vowels and consonants in a string

In this post, we are going to learn how to write a program to  count total number of vowels and consonants in given string input from user in Java language

Code to count Vowels or consonants in a string

Code to count number of Vowel and consonant in a string, using for loop   – #1

In this code, we are going to learn how to count  the total number of  Vowel and consonant in the given String using for loop in Java language

Program 1

import java.util.Scanner;
public class CountVowelsAndConsonants{
public static void main(String args[]){
  String str;//declare a string
int vowCount=0,consCount=0;

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter the String for count vowel and consonant  ");
//Ask input from uer as string
str=scan.nextLine();//reading the input
int i=0; 
for(i=0; i<str.length(); i++){
  char ch=str.charAt(i);
  if(ch == 'a'|| ch == 'e'|| ch == 'i'|| ch == 'o'|| ch == 'u'
  ||ch == 'A'|| ch == 'E'|| ch == 'I'|| ch == 'O'|| ch == 'U' ){
    vowCount++;
  }
  else if((ch >= 'a' && ch <= 'z' || ch >= 'A' && ch <= 'Z' )){
    consCount++;
  }
}
System.out.println("Number of vowels: "+vowCount);
//display number of vowels
System.out.println("Number of consonant: "+consCount);
//display number of consonants
}
}

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

Enter the String for count vowel and consonant
My Java
Number of Vowels: 2
Number of consonant: 4

 

Code to count number of Vowel and consonant in a string, using while loop   – #2

In this code, we are going to learn how to count  the total number of  Vowel and consonant in the given string using while loop in Java language

Program 2

import java.util.Scanner;
public class CountVowelsAndConsonants1{
public static void main(String args[]){
  String str;//declare character variable
int vowCount=0,consCount=0;
//initiolize variables vowCount and consCount as zero
 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter the String for count vowel and consonant  ");
//Ask input from user as string
str=scan.nextLine();//reading the string input
int i=0; 
while(i<str.length()){
  char ch=str.charAt(i);
  if(ch == 'a'|| ch == 'e'|| ch == 'i'|| ch == 'o'|| ch == 'u'
  ||ch == 'A'|| ch == 'E'|| ch == 'I'|| ch == 'O'|| ch == 'U' ){
    vowCount++;
  }
  else if((ch >= 'a' && ch <= 'z' || ch >= 'A' && ch <= 'Z' )){
    consCount++;
  }
   i++;
}
System.out.println("Num ber of vowels: "+vowCount);
//display number of vowels in the given string
System.out.println("Num ber of consonant: "+consCount);
//display number of consonant in the given string
}
}

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

Enter the String for count vowel and consonant
Programming
Number of Vowels: 3
Number of consonant: 8

 

Code to count number of Vowel and consonant in a string, using do-while loop   – #3

In this code, we are going to learn how to count  the total number of  Vowel and consonant in the given string using do-while loop in Java language

Program 3

import java.util.Scanner;
public class CountVowelsAndConsonantsAscii{
public static void main(String args[]){
  String str;//declare a string variable
int vowCount=0,consCount=0;
//initialize counter variable
 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter the String for count vowel and consonant  ");
str=scan.nextLine();
int i=0; 
for(i=0; i<str.length(); i++){
  char ch=str.charAt(i);
  if(ch == 97|| ch == 101|| ch == 105|| ch == 111|| ch == 117
  ||ch == 65|| ch == 69|| ch == 73|| ch == 79|| ch == 85 ){
    vowCount++;
  }
  else if((ch >= 97 && ch <= 122 || ch >= 65 && ch <= 90 )){
    consCount++;
  }
}
System.out.println("The number of vowels: "+vowCount);
System.out.println("The number of consonant: "+consCount);
}
}

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

Enter the String for count vowel and consonant
Vowels and consonants
The number of vowels: 6
The number of consonants: 13
