How to find the vowels in a given string using Java?
You can read a character in a String using the charAt() method. To find the vowels in a given String you need to compare every character in it with the vowel letters.
Example
public class FindingVowels {
public static void main(String args[]) {
String str = new String("Hi Welcome to Tutorialspoint");
for(int i=0; i<str.length(); i++) {
if(str.charAt(i) == 'a'|| str.charAt(i) == 'e'|| str.charAt(i) == 'i' || str.charAt(i) == 'o' || str.charAt(i) == 'u') {
System.out.println("Given string contains "+str.charAt(i)+" at the index "+i);
}
}
}
}
Output
Given string contains i at the index 1 Given string contains e at the index 4 Given string contains o at the index 7 Given string contains e at the index 9 Given string contains o at the index 12 Given string contains u at the index 15 Given string contains o at the index 17 Given string contains i at the index 19 Given string contains a at the index 20 Given string contains o at the index 24 Given string contains i at the index 25
