adding string to certain char

Question

doing a lab for class ( cannot use ARRAY )** its a langue converter and i have to put 'ub' after every vowel i was wondering how i could do this WITHOUT AN ARRAY so far i have but it just adds "ub" after the second letter in a string

private static String toUbbi(String word ) {            
    String set = " ";
    if (Vowel (word)){
        set=  word.substring(0)+ "ub"+word.substring(1) ;
        set = word.substring(0,1)+ "ub"+word.substring(1);
    }
    return set;         
}     

private static boolean Vowel(String word ) {             
String[] vowels ={ "a", "e", "i", "o", "u", "ue"} ; 
    //char x = word.charAt(0);
    return (vowels.length !=-1);     
}

What I would do is basically use a "target" String into which you can append the changes, substring each prefix section (up to the next vowel). This gets added to the "target" and "ub". Remove this prefix from the original String and continue until the original String is 0 in length and/or no vowles remain. Assign the target to the original and return... — MadProgrammer

String word = "test";
String[] vowels ={ "a", "e", "i", "o", "u"}
for (int i = (vowels.length - 1); i>=0; i-- ){

    word = word.replaceAll(vowel[i], vowel[i].concat("ub"));
}

You can try this:

public static void main(String[] args)
{
    String str = "christian";
    String new_str = "";

    for (int i = 0; i < str.length(); i++) {
        new_str += str.charAt(i);
        if (isVowel(str.charAt(i))) // If is a vowel
            new_str += "ub";
    }
    System.out.println(new_str);
}

private static boolean isVowel(char c)
{
    if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')
        return true;
    return false;
}
