Week 2: Methods, strings and lists/14. Remove vowels

Write the method

String removeVowels(String word)

which returns a string with all vowels (a, e, i, o, u and y) removed from the string given as a parameter.



You can assume that the word is written entirely in lower case.
Example of a method call:
public static void main(String[] args) {
    String testword = "welcome!";
    System.out.println(removeVowels(testword));
}
Program outputs:
wlcm!



======================================


import java.util.Random;

public class Test{
    public static void main(String[] args){
        final Random r = new Random();
        
        
        String[] words = "first second third fourth programming class method java variable".split(" ");
        for (String word : words) {
            System.out.println("Testing with parameter " + word);
            System.out.println("Without vowels: " + removeVowels(word));
            System.out.println("");
        }
        
    }


    //ADD
    public static String removeVowels(String word) {
        String newWord = "";
        
        // if the character is not a/e/i/o/u/y - then add to newWord
        for (int i = 0; i < word.length(); i++) {
            if (word.charAt(i) != 'a' 
                && word.charAt(i) != 'e' 
                && word.charAt(i) != 'i' 
                && word.charAt(i) != 'o' 
                && word.charAt(i) != 'u' 
                && word.charAt(i) != 'y') {
                    newWord += word.charAt(i);
            }
        }
        return newWord;
    }
