    char[] replaceChar = {'a','e','i','o','u'};

    public static void main(String[] args) {
        String src = "Battle of the Vowels:Hawaii vs Gronzy";
        System.out.println(new RemoveChars().removeChar(src));
    }

    public String removeChar(String src){
        char[] srcArr = src.toCharArray(); 
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < srcArr.length; i++) {
            char foundChar = isFound(srcArr[i]);
            if(foundChar!='\0')
            sb.append(foundChar);           
        }
        return sb.toString();

    } 

    public char isFound(char src){      
        for (int i = 0; i < replaceChar.length; i++) {
            if(src==replaceChar[i]){
                return '\0';
            }
        }
        return src;
    }
