How to find consonants in a given string using Java?

One way to find the vowels in a given String is to compare every character in it using the charAt() method with the vowel letters.

Example

Live Demo

public class FindingConsonants {
   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'|| str.charAt(i) == ' ') {
         } else {
            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
