String Minipulation
Hey Everyone!
I found this tutorial the other day dealing with converting english to piglatin, but I can't find it for the life of me now. I'm really interested in doing it and I thought I'd stop by here to get some advice on what actually needs to be done.
I'm just trying to get an idea on what needs to be done and with what. For example, here is something that has to be looked for in the user input.
--------------------------
For words that begin with a vowel (a,e,i,o,or u) and end with a vowel. First, add a y at the beginning of the word. Then add yay at the end.
For example: User inputs a word like, 'orange'. Output would be 'yorangeyay'
--------------------------
I'm just trying to get an idea on what I need to use to get it going or what it would look like and possibly what you think about when you see a problem like this.
Regards,
David McGraw

Here you get the User Input in to a string
>>>>args[0];
convert to a CharArray();
then take the first character of that array and then check whether the letter is a vowel or not
if it is a vowel then you add a letter y to the from of that array.
then move to a last character of that array and again check for the vowel or not and repeat the same

Alright! Im back from vacation and I've trying to work on this tutorial. So far I've set up the foundation, but geez, as far as understanding how to implement this is proving to be a difficult task. Here is the small portion of this that I've worked so far. Im trying to set it up in MCV architecture to be able to add it to my reference library of tutorials. Here is what Ive gotten so far;
Any different ways to explain this would help greatly.
Thanks,
Dave

In the VIEW class:-

try out this one..........
while ((str = input.readLine()) != null)
{
// Do proecessing of the Input String from the User......
}
In the CheckVowel Mehtod implement the code for checking the String you get from the User............

Well the reason I did it that was mainly for the MCV understanding. Wouldn't I use the Model method to do the while statement (the central part of the program)?

Maybe this will be easier for me to understand. Here the actual tutorial, but its using a GUI that I really dont want to get into yet because im trying to get the basics down first. If it would be easier, could you edit it, or would that not be easy? I'm not sure what needs removed/replaced.

I'm not so much interested into seing the whole code, but rather more interested into understanding how you read a word like, 'orange' , and then seeing that it begins and ends with a vowel, and then putting y on the front of the word and yay on the end of the word.
Thank you,
David McGraw
