Question

/**

* Returns the result of converting s to "Pig Latin". Convert a string s to Pig Latin by using the following rules:

*

* (1) If s contains no vowels, do nothing to it.

*

* (2) Otherwise, if s starts with a vowel, append "way" to the end.

*

* (3) Otherwise, move everything up to (but not including) the first vowel to the end and add "ay".

*

* For example, "hello" converts to "ellohay", "small" converts to "allsmay", "eat" converts to "eatway", and "nth"

* converts to "nth".

*

* IMPLEMENTATION NOTE: This will require a three-way conditional that extracts pieces of Strings and recombines

* them into new Strings. For full credit (and an easier implementation), use the firstVowelIndex method provided

* above in your method's implementation. You will also find the methods s.substring() and s.charAt() (where s is a

* String), as well as the + operator that concatenates Strings, very useful.

return "";

Answer 1

Have in mind that you didn't include the firstVowelIndex method provided, which is required for full credit. However, I implemented one assuming it would be static, however, if the one the problem provides is static, you can remove my implementation from the code, just the -public static Integer firstVowelIndex (String s)- block but, if it is not static, then you would have to change inside toPigLatin method, where it says firstVowelIndex(s) to s.firstVowelIndex()

public class Main {

    public static void main(String[] args){
        String test="nth";
        toPigLatin(test);
    }

    public static String toPigLatin (String s)
    {
        String back="";
        String ending="";
        String part="";
        Boolean flag=false;
        for (int i=0;i<s.length();i++){
            char c=s.charAt(i);
            if (c=='A' || c=='E' || c=='I' || c=='O' || c=='U' || c=='a' || c=='e' || c=='i' || c=='o' || c=='u'){
                flag=true;
                back=s;
                break;
            }
        }

        if (flag){
            if (firstVowelIndex(s)==0){
                ending="way";
                back=s+ending;
            }
            else
            {
                ending="ay";
                for (int i=0; i<firstVowelIndex(s);i++) {
                    part=part+s.charAt(i);
                }
                back=s.substring(firstVowelIndex(s))+part+ending;
            }
        }
        else
        {
            back=s;
        }
        System.out.println(back);
        return back;
    }

    public static Integer firstVowelIndex (String s)
    {   int index=-1;
        for (int i=0; i < s.length(); i++){
            char c= s.charAt(i);
            if (c=='A' || c=='E' || c=='I' || c=='O' || c=='U' || c=='a' || c=='e' || c=='i' || c=='o' || c=='u'){
                index=i;
                break;
            }
        }
        return index;
    }
