Here you will learn that how to make a java program to count number of vowels in a string using string length method.

There are 5 vowels in the English alphabet that’s are a,e,i,o,u. let’s do this program by using java programming.

Java Program to Count Number of Vowels in a String

import java.util.*;

public class CountVowels

{

public static void main(String []args)

{

String str;

int k,ct=0;

Scanner in = new Scanner(System.in);

System.out.print("Enter a sentence : ");

str = in.nextLine();

for(k=0;k<str.length();k++)

{

if(str.charAt(k) == 'a' || str.charAt(k) == 'e' ||

str.charAt(k) == 'i' || str.charAt(k) == 'o' ||

str.charAt(k) == 'u' || str.charAt(k) == 'A' ||

str.charAt(k) == 'E' || str.charAt(k) == 'I' ||

str.charAt(k) == 'O' || str.charAt(k) == 'U')

{

ct++;

}

System.out.println("Total Vowels are :"+ct);
